Data printing methods, apparatus, storage media, and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 2025100790484, filed on January 17, 2025, entitled “Data Printing Method, Apparatus, Storage Medium and Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] In related technologies, since different users have different printing needs and printer memory is limited, in order to meet the printing needs of all users, the data to be printed is sent from the user's device to the printer via Bluetooth or other means to achieve the function of printing while receiving data.

[0004] During a single printing process, users may print multiple pages and send the entire contents of each page to the printer. For some high-speed printers, the printing speed may exceed the data sending speed, causing the printer to frequently pause and wait for data to be printed during a single printing session, resulting in low printer efficiency. Therefore, improving printer efficiency is a pressing technical problem that needs to be solved.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this application, it should be noted that, unless otherwise expressly specified and limited, "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0041] Please refer to Figure 1, which is a schematic diagram of a data printing system provided in an embodiment of this application. As shown in Figure 1, the data printing system may include at least a client cluster and a printing device 100.

[0042] In some embodiments, the client cluster may include at least one client, as shown in Figure 1, specifically including client 1 corresponding to user 1, client 2 corresponding to user 2, ..., client n corresponding to user n, where n is an integer greater than 0.

[0043] Each client in a client cluster can be an electronic device with communication capabilities, including but not limited to: wearable devices, handheld devices, personal computers, tablets, in-vehicle devices, smartphones, computing devices, or other processing devices connected to a wireless modem. Electronic devices may have different names in different networks, such as: user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, cellular phone, cordless phone, personal digital assistant (PDA), and electronic devices in 5G networks or future evolved networks.

[0044] Printing device 100 is an output device used to print digital information onto a relevant medium. Its basic working principle is to control a print head or laser through signal processing to form characters or images on the transmitted paper using ink or toner. Printing device 100 may include, but is not limited to, inkjet printers, laser printers, thermal printers, dot matrix printers, and thermal transfer printers. The printing principles of the different types of printers mentioned above are as follows: Inkjet printers print text and images by spraying liquid ink onto paper; laser printers use a laser beam to draw the image or text to be printed on a photosensitive drum, then use electrical charge to attract toner (carbon powder) onto the image, and finally transfer the toner to the paper, fixing it onto the paper by heating; thermal printers form images or text by heating a special coating on thermal paper; thermal paper itself contains heat-reactive substances, and when the print head is heated, the coating on the paper surface undergoes a chemical reaction, displaying patterns or text; dot matrix printers print a series of small dots in columns on the paper using a print head, and these dots combine to form letters, numbers, and symbols; thermal transfer printers use a heat exchanger to transfer toner or ink from a strip material (such as a thermal transfer tape) to the paper, and the print head heats the ink on the tape and transfers it to the target surface to form the printed content.

[0045] In one or more embodiments of this application, the printing device 100 can establish a communication connection with at least one client in the client cluster, and complete data interaction during the data printing process based on the communication connection. For example, the printing device obtains and stores the previous page print data; the client determines the target difference print data corresponding to the current page print data and the previous page print data in the current page print data; the printing device determines the data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. The previous page print data and the target difference print data can be obtained from the client after the printing device establishes a communication connection with the client.

[0046] It should be noted that the printing device 100 establishes a communication connection with at least one client in the client cluster via a network for interactive communication. This network can be a wireless network or a wired network. Wireless networks include, but are not limited to, cellular networks, wireless LANs, infrared networks, or Bluetooth networks. Wired networks include, but are not limited to, Ethernet, universal serial bus (USB), or controller area networks. In one or more embodiments of the specification, technologies and / or formats including Hyper Text Markup Language (HTML), Extensible Markup Language (XML), etc., are used to represent data exchanged over the network (such as target compressed packets). Furthermore, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) can be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can be used to replace or supplement the aforementioned data communication technologies.

[0047] The data printing system embodiments provided in this specification and the data printing methods described in one or more embodiments belong to the same concept. The execution entity corresponding to the data printing method involved in one or more embodiments of this specification can be an electronic device, which can be the aforementioned printing device 100 or the aforementioned client, depending on the actual application environment. The specific implementation process of the data printing system embodiments can be found in the following method embodiments, and will not be repeated here.

[0048] In one embodiment, as shown in Figure 2, a data printing method is proposed. This method can be implemented using a computer program and can run on a data printing device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application.

[0049] Specifically, the data printing method includes:

[0050] S201, retrieve the previous page print data and store the previous page print data.

[0051] In this context, "previous page print data" refers to at least a portion of the data on a single page of a multi-page print job. This previous page print data is in a specific format that can be recognized and printed by the printing device. For example, the previous page print data could be at least a portion of the data on any page of a multi-page print job, excluding the last page. It can be understood that the previous page print data could be all the data on a single page to be printed, or it could be a portion of the data on that single page.

[0052] In some embodiments, the printing device can obtain the previous page print data from the client and then store the previous page print data locally. Specifically, the client can install printing software that communicates with, manages, and operates the printing device. The user can trigger a print job in the printing software, the client generates a print command corresponding to the print job, and the client sends the previous page print data corresponding to the user-triggered print job to the printing device based on the print command.

[0053] Understandably, printing devices can be configured with data buffer areas to store different data types of print data. For example, a printing device can be configured with a complete data buffer area and a partial data buffer area. The complete data buffer area can store all the data for a single page to be printed, while the partial data buffer area can store a portion of the data for a single page or a portion of the data for multiple pages to be printed. If the previous page of print data is all the data for a page to be printed, then the printing device can store the previous page's print data in the complete data buffer area. If the previous page of print data is only a portion of the data for a page to be printed, then the printing device can store the previous page's print data in the partial data buffer area.

[0054] S202, determine the target difference print data between the current page print data and the previous page print data in the current page print data.

[0055] The current page print data refers to the print data located after the previous page print data, determined according to the printing order of the data to be printed.

[0056] Target difference print data refers to the difference in print data between two adjacent pages; it can be understood as different data between two adjacent pages. In this embodiment, the current page print data and the complete page print data corresponding to the previous page print data are two adjacent pages. By comparing the current page print data and the complete page print data corresponding to the previous page print data, we can obtain print data that exists at the target page position in the current page print data but does not exist at the target page position in the complete page print data corresponding to the previous page print data; this is the target difference print data.

[0057] For example, the current page print data is split into a preset number of lines based on the page layout and the print head precision of the printing device. The complete page print data corresponding to the previous page print data is also split into a preset number of lines based on the page layout and the print head precision of the printing device. Assuming the preset number of lines is 500, the data from lines 410 to 425 in the 500 lines obtained from splitting the current page print data are different from the data from lines 410 to 425 in the 500 lines obtained from splitting the complete page print data corresponding to the previous page print data. The data in the remaining lines are exactly the same. Therefore, the data from lines 410 to 425 in the 500 lines obtained from splitting the current page print data is the target difference print data.

[0058] Understandably, if the previous page of printed data contains all the data from a page to be printed, then the complete page of printed data corresponding to the previous page is the previous page of printed data itself. If the previous page of printed data contains only a portion of the data from a page to be printed, then the complete page of printed data corresponding to the previous page is determined by both the previous page of printed data and the page of printed data preceding it.

[0059] In some embodiments, after the printing device stores the previous page of print data, the printing device processes the previous page of print data. After all the previous page of print data has been printed, or after a preset time has elapsed since the printing time of the target row of print data in the previous page of print data has elapsed, the printing device can send a data preparation instruction to the client. After receiving the data preparation instruction, the client obtains the current page of print data, determines the target difference print data between the current page of print data and the complete page of print data corresponding to the previous page of print data, and further sends the target difference print data to the printing device.

[0060] In some other embodiments, after the client sends the previous page print data to the printing device, the client can obtain the current page print data, determine the target difference print data between the current page print data and the complete page print data corresponding to the previous page print data in the current page print data, and further, the client directly sends the target difference print data to the printing device.

[0061] Optionally, the previous page of print data obtained by the printing device from the client can be multi-line data obtained by the client after splitting the data according to the print head resolution of the printing device. When splitting the data, the client first determines the print head resolution and print width, then calculates the number of dots that can be printed per line based on these parameters. Finally, the entire page of data to be printed is split into multiple lines according to the number of dots that can be printed per line. Here, print head resolution refers to the resolution of the printing device, used to express the number of dots that the print head can print per inch; print width refers to the maximum width that the printing device can print per line, usually measured in millimeters or inches.

[0062] S203, determine the data storage area for the target difference print data, store the target difference print data in the data storage area, determine the target print data based on the target difference print data, and perform print processing on the target print data.

[0063] The data storage area may include at least one of a complete data cache area and a partial data cache area.

[0064] In some embodiments, the printing device can receive target difference print data sent by the client. The printing device can determine the data storage area for the target difference print data based on its data type. When the target difference print data is of a complete data type, the printing device can store the target difference print data in the complete data cache area if it determines that the complete data cache area is idle. Then, it reads the latest print data from the complete data cache area for printing. The latest print data read from the complete data cache area is the target print data; that is, when the target difference print data is of a complete data type, the target print data is the target difference data. When the target difference print data is of a non-complete data type, the printing device can store the target difference print data in a partial data cache area. If it determines that the complete data cache area is idle, the printing device can determine the target storage location of the target difference print data in the complete data cache area, copy the target difference print data to the target storage location, and then read all print data from the complete data cache area to obtain the latest print data for printing. In this case, all print data in the complete data cache area is the target print data; that is, when the target difference print data is of a non-complete data type, the target difference data is a portion of the target print data.

[0065] It's understandable that a fully loaded data buffer being idle means that there is no unprinted data in the printing device; that is, all the printed data stored in the printing device has been printed. Only when the fully loaded data buffer is idle can new data be written to it. At this point, the printing device can store data that needs to be stored in the fully loaded data storage area.

[0066] In the data printing method provided in this application embodiment, the printing device acquires and stores the previous page's print data. The client determines the target difference print data corresponding to the current page's print data and the previous page's print data from the current page's print data. The printing device determines the data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. Therefore, by having the client determine the target difference print data corresponding to the print data of adjacent pages, the printing device only needs to receive the target difference print data and not the current page's print data. This reduces the amount of print data acquired by the printing device during the printing process, avoids the problem of frequent pauses and waiting for print data during a single printing process, and enables the printing device to print continuously and stably, improving the printing device's working efficiency.

[0067] Please refer to Figure 3, which provides a flowchart of another data printing method according to an embodiment of this application.

[0068] Specifically, the data printing method includes:

[0069] S301, retrieve the previous page print data and store the previous page print data.

[0070] S302, determine the target difference print data between the current page print data and the previous page print data in the current page print data.

[0071] Specifically, the implementation methods of S301 and S302 can be found in the description of the relevant parts in the embodiment shown in Figure 2, and will not be described in detail here.

[0072] S303, obtain the target printing instruction corresponding to the target difference printing data.

[0073] In some embodiments, where the previous page print data and the target difference print data are obtained by the printing device from the client, the printing device may also obtain the target print instruction from the client. After determining the target difference print data, the client can generate the target print instruction and send it to the printing device. Specifically, the target print instruction may include print parameters related to the target difference print data. These parameters may include, but are not limited to, print width, print height, and data type. Print width and print height refer to the width and height occupied on the print page after the current page print data is printed using the target difference data. The data type indicates whether the target difference print data is of a complete or incomplete data type.

[0074] S304, if the target difference print data is determined to be of the data integrity type based on the target print instruction, then the integrity data cache area is determined as the data storage area for the target difference print data.

[0075] Understandably, the complete data buffer area is a buffer area specifically configured in the printing device to store all the print data for a single sheet. After the printing device determines that the target difference print data is of the complete data type, it designates the complete data buffer area as the data storage area for the target difference print data.

[0076] S305, if the target difference print data is determined to be of incomplete data type based on the target print instruction, then the partial data cache area is determined as the data storage area for the target difference print data.

[0077] It is understandable that a partial data buffer area is a portion of the printed data specifically configured in the printing device to store at least one sheet of paper. The storage capacity of the partial data buffer area can be equal to the storage capacity of the full data buffer area, or it can be greater than or less than the storage capacity of the full data buffer area.

[0078] For example, a print job requires printing 3 pages. The print data of the 2nd page differs from that of the 1st page, and the print data of the 3rd page differs from that of the 2nd page. The first difference in print data between the 2nd page and the 1st page can be identified from the print data of the 2nd page, and the second difference in print data between the 3rd page and the 2nd page can be identified from the print data of the 3rd page. The storage capacity of a partial data cache area is sufficient to store the first and second difference print data.

[0079] Specifically, after the printing device determines that the target difference print data is of the incomplete data type, the printing device determines a partial data cache area as the data storage area for the target difference print data.

[0080] S306, store the target difference print data to the data storage area.

[0081] Specifically, when the target difference print data is of the data complete type, the printing device, after determining that the complete buffer area is in an idle state, retrieves all single-line data and their corresponding line number identifiers from the target difference print data. It then determines the row storage location corresponding to each line number identifier within the complete data buffer area and stores the single-line data corresponding to each line number identifier in that location. It can be understood that an idle complete buffer area means that there is no unprinted print data in the printing device; that is, all the print data stored in the printing device has been printed.

[0082] When the target difference print data is of incomplete data type, the printing device obtains all single-line data and the corresponding line number identifiers from the target difference print data, stores the line number identifiers and single-line data in a one-to-one correspondence in the partial data cache area, and records the storage address of these single-line data in the partial data cache area.

[0083] It is understood that the data storage area includes at least one of a complete data buffer area and a partial data buffer area. The complete data buffer area stores all the printing data for a single sheet, while the partial data buffer area stores partial printing data for at least one sheet. Specifically, the complete data buffer area can be configured such that its starting buffer position corresponds to the end position along the length of the paper, and its ending buffer position corresponds to the end position along the length of the paper. Thus, during the printing process, as the printing device reads printing data starting from the starting buffer position of the complete data buffer area, the printing position of the data can proceed from the end position along the length of the paper to the end position, ensuring that the content printed on the paper conforms to the user's reading habits.

[0084] S307, determine the target print data based on the target difference print data, determine the number of reprints corresponding to the target difference print data from the target print instruction, and perform reprint processing on the target print data according to the number of reprints.

[0085] In some embodiments, where the previous page print data and the target difference print data are obtained by the printing device from the client, the print parameters in the target print instruction obtained by the printing device from the client may also include the number of reprints corresponding to the target difference print data. The number of reprints refers to the number of times the current page print data, including the target difference print data, is reprinted. When the target difference print data is the current page print data, all print data is read from the complete data cache area, and all print data in the complete data cache area is used as the target print data. The printing device then performs reprint processing on the target print data according to the number of reprints. When the target difference print data is a portion of the current page print data, the printing device needs to copy the target difference print data from the partial data cache area to the corresponding position in the complete data cache area. The printing device then reads all print data from the complete data cache area, and all print data in the complete data cache area is used as the target print data. The printing device then performs reprint processing on the target print data according to the number of reprints.

[0086] In the data printing method provided in this application embodiment, the printing device acquires and stores the previous page print data. The client determines the target difference print data corresponding to the current page print data and the previous page print data in the current page print data. The printing device acquires the target print instruction corresponding to the target difference print data. If the target difference print data is determined to be of the data integrity type based on the target print instruction, the integrity data cache area is determined as the data storage area of ​​the target difference print data. If the target difference print data is determined to be of the data incomplete type based on the target print instruction, the partial data cache area is determined as the data storage area of ​​the target difference print data. The target difference print data is stored in the data storage area. The target print data is determined based on the target difference print data. The number of reprints corresponding to the target difference print data is determined from the target print instruction. The target print data is then reprinted according to the number of reprints. Therefore, by determining the target difference print data corresponding to the print data of adjacent pages through the client, and generating the target print command through the client, the printing device only needs to receive the target difference print data and does not need to receive the current page print data or the duplicate print data. This not only greatly reduces the amount of print data acquired by the printing device during the printing process, avoiding the problem of the printing device frequently pausing and waiting for print data during a single printing process, but also saves the time of the printing device in determining the data storage area of ​​the target difference print data, further improving the working efficiency of the printing device.

[0087] Please refer to Figure 4, which provides a flowchart of another data printing method according to an embodiment of this application.

[0088] Specifically, the data printing method includes:

[0089] S401, retrieve the previous page print data and store the previous page print data.

[0090] Specifically, the implementation of S401 can be found in the description of the relevant parts in the embodiment shown in Figure 2, and will not be detailed here.

[0091] S402, perform line-by-line data comparison between the current page print data and the previous page print data to obtain the target difference print data.

[0092] In some embodiments, where the previous page print data is all the data of a certain page to be printed, after the client sends the previous page print data to the printing device, it can determine the current page print data following the previous page print data according to the printing order, generate a target image of a preset format from the current page print data, split the target image into rows to obtain multiple rows of data corresponding to the current page print data, and perform row-by-row comparison processing between the multiple rows of data corresponding to the current page print data and the multiple rows of data corresponding to the previous page print data to obtain the target difference print data. Understandably, the multi-line data corresponding to the current page print data is the preset number of lines, and the multi-line data corresponding to the previous page print data is also the preset number of lines. For example, if the preset number of lines is 500, after line-by-line data comparison, it is confirmed that the data from lines 480 to 500 in the multi-line data corresponding to the current page print data is different from the data from lines 480 to 500 in the multi-line data corresponding to the previous page print data. Then, the data from lines 480 to 500 in the multi-line data corresponding to the current page print data is determined as the target difference print data. The target difference print data can include the line data with differences and the line number identifier corresponding to the line data.

[0093] Optionally, if the previous page print data is a portion of the data to be printed, after sending the previous page print data to the printing device, the client can determine the current page print data following the complete page print data corresponding to the previous page print data according to the printing order. The current page print data can then generate a preset target image. This target image can be split into rows to obtain multiple rows of data corresponding to the current page print data. These multiple rows of data can then be compared row by row with the multiple rows of data corresponding to the complete page print data to obtain the target difference print data.

[0094] S403, determine the data storage area for the target difference print data, store the target difference print data in the data storage area, determine the target print data based on the target difference print data, and perform print processing on the target print data.

[0095] Specifically, the implementation of S403 can be found in the description of the relevant parts in the embodiment shown in Figure 2, and will not be detailed here.

[0096] In the data printing method provided in this application embodiment, the printing device acquires and stores the previous page's print data. The client performs line-by-line data comparison processing between the current page's print data and the previous page's print data to obtain target difference print data. The printing device determines the data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. Therefore, by performing line-by-line data comparison processing between the current page's print data and the previous page's print data, the client can accurately determine the target difference print data, enabling the accurate target difference print data to be sent to the printing device. This reduces the amount of print data acquired by the printing device while ensuring the accuracy of the printed data.

[0097] Please refer to Figure 5, which provides a flowchart of another data printing method according to an embodiment of this application.

[0098] Specifically, the data printing method includes:

[0099] S501, retrieve the previous page print data and store the previous page print data.

[0100] S502, determine the target difference print data between the current page print data and the previous page print data in the current page print data.

[0101] S503, Determine the data storage area for the target difference print data.

[0102] Specifically, the implementation methods of S501-S503 can be found in the description of the relevant parts in the embodiment shown in Figure 2, and will not be elaborated here.

[0103] S504, if the target difference print data is of incomplete data type, store the target difference print data in the partial data cache area, determine the target storage location of the target difference print data in the complete data cache area, copy the target difference print data to the target storage location to obtain the first target print data in the complete data cache area, and perform printing processing on the first target print data.

[0104] In some embodiments, when the target difference print data is of an incomplete data type, the printing device stores the target difference print data in a partial data cache area. When the printing device determines that the complete data cache area is idle, it determines the target storage location of the target difference print data in the complete data cache area, copies the target difference print data to the target storage location to obtain the first target print data in the complete data cache area, and performs printing processing on the first target print data.

[0105] Specifically, the process involves determining the target storage location of the target difference print data within the complete data cache area, copying the target difference print data to the target storage location to obtain the first target print data in the complete data cache area, and then printing the first target print data. This process may include:

[0106] In the target difference print data, determine at least one line of difference print data and the corresponding line number identifier. In the complete data cache area, determine the target storage location indicated by the line number identifier. Use at least one line of difference print data to overwrite and update the data in the target storage location to obtain the first target print data in the complete data cache area. Start reading the first target print data from the starting cache position in the complete data cache area and start printing.

[0107] S505, if the target difference print data is of the data complete type, after all the stored print data has been printed, the target difference print data is stored in the complete data cache area to obtain the second target print data, and the second target print data is printed.

[0108] In some embodiments, when the target difference print data is of the data integrity type, the printing device first determines whether there is any stored print data that has not been printed completely. If there is stored print data that has not been printed completely, the printing device sends a no-memory instruction to the client to inform the client that the printing device does not currently have memory to store the target difference print data and to instruct the client to send the target difference print data to the printing device only when it receives a memory instruction. If there is no stored print data that has not been printed completely, that is, all stored print data has been printed completely, then the target difference print data is stored in the complete data buffer area to obtain the second target print data, and the second target print data is printed.

[0109] Specifically, the process of storing the target difference print data into the complete data cache area to obtain the second target print data, and then printing the second target print data, may include:

[0110] In the target difference print data, determine at least one line of difference print data and the corresponding line number identifier of at least one line of difference print data. Write at least one line of difference print data to the storage location indicated by the line number identifier in the complete data cache area to obtain the second target print data in the complete data cache area. Start reading the second target print data from the starting cache position in the complete data cache area and start printing.

[0111] In the data printing method provided in this application embodiment, the printing device acquires and stores the previous page's print data. The client determines the target difference print data corresponding to the previous page's print data from the current page's print data. If the target difference print data is of incomplete data type, the printing device stores the target difference print data in a partial data cache area, determines the target storage location of the target difference print data in the complete data cache area, copies the target difference print data to the target storage location to obtain the first target print data in the complete data cache area, and prints the first target print data. If the target difference print data is of complete data type, the printing device stores the target difference print data in the complete data cache area after all stored print data has been printed to obtain the second target print data, and prints the second target print data. Therefore, by configuring different storage areas in the printing device to store target difference print data of different data types sent by the client, the amount of print data received by the printing device can be reduced while ensuring that the printing device can accurately reconstruct the current page's print data based on the target difference print data, thus guaranteeing the accuracy of data printing.

[0112] Please refer to Figure 6, which provides a flowchart of another data printing method according to an embodiment of this application.

[0113] Specifically, the data printing method includes:

[0114] S601, retrieve the previous page print data, and determine whether the previous page print data is the first page print data.

[0115] The first page print data can be understood as the first page of print data received by the printing device in this print job. Specifically, the first page print data can be the first page of all data to be printed in this print job, arranged in the order of printing.

[0116] In some embodiments, after the printing device obtains the previous page print data from the client, the printing device can determine whether other page print data was received before receiving the previous page print data after the current print job was started, in order to determine whether the previous page print data is the first page print data. If no other page print data was received before receiving the previous page print data after the current print job was started, then the previous page print data can be determined to be the first page print data. If other page print data was received before receiving the previous page print data after the current print job was started, then the previous page print data can be determined not to be the first page print data.

[0117] S602, if the previous page print data is the first page print data, then store the previous page print data in the complete data cache area.

[0118] In some embodiments, after determining that the previous page print data is the first page print data, the printing device can obtain multiple lines of data and the line number identifier corresponding to each line of data from the previous page print data, obtain the start cache position and end cache position of the complete data cache area, and store each line of data corresponding to the line number identifier sequentially from the start cache position until the last line of data is stored at the end cache position, thus completing the storage process of the previous page print data.

[0119] S603, if the previous page print data is not the first page print data, then determine the reference data type corresponding to the previous page print data, determine the reference data storage area of ​​the previous page print data based on the reference data type, and store the previous page print data in the reference data storage area.

[0120] In some embodiments, after determining that the previous page print data is not the first page print data, the printing device can determine the reference data type of the previous page print data based on the print instruction corresponding to the previous page print data received from the client. When the reference data type is determined to be a complete data type, the reference data storage area is determined to be a complete data cache area. Further, if the printing device confirms that the complete data cache area is idle, the previous page print data is stored in the complete data cache area. When the reference data type is determined to be a non-complete data type, the reference data storage area is determined to be a partial data cache area. Further, the printing device directly stores the previous page print data in the partial data cache area and records the storage location of the previous page print data in the partial data cache area so that data can be read from the partial data cache area according to the storage location when printing the previous page print data later.

[0121] S604, determine the target difference print data between the current page print data and the previous page print data in the current page print data.

[0122] S605, determine the data storage area for the target difference print data, store the target difference print data in the data storage area, determine the target print data based on the target difference print data, and perform print processing on the target print data.

[0123] Specifically, the implementation methods of S604 and S605 can be found in the description of the relevant parts in the implementation shown in Figure 2, and will not be elaborated here.

[0124] In the data printing method provided in this application embodiment, the printing device acquires the previous page print data, determines whether the previous page print data is the first page print data, and if the previous page print data is the first page print data, stores the previous page print data in the complete data cache area. If the previous page print data is not the first page print data, determines the reference data type corresponding to the previous page print data, determines the reference data storage area for the previous page print data based on the reference data type, and stores the previous page print data in the reference data storage area. The client determines the target difference print data corresponding to the current page print data and the previous page print data in the current page print data. The printing device determines the data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. Therefore, by determining whether the previous page print data is the first page print data and then deciding whether to determine the storage area for the previous page print data based on the data type, the printing device can save time in determining the storage area for the previous page print data. This further improves the working efficiency of the printing device by reducing the amount of print data received by the printing device to avoid the problem of the printing device frequently waiting for print data.

[0125] Please refer to Figure 7, which provides a flowchart of another data printing method according to an embodiment of this application.

[0126] Specifically, the data printing method includes:

[0127] S701, retrieve the previous page print data and store the previous page print data.

[0128] Specifically, the implementation of S701 can be found in the description of the relevant parts in the implementation shown in Figure 2, which will not be elaborated here.

[0129] S702, after all the print data on the previous page has been printed, determine the target difference print data between the print data on the current page and the print data on the previous page.

[0130] In some embodiments, after sending the previous page of print data to the printing device, the client can continuously send print completion query commands corresponding to the previous page of print data to the printing device. After the printing device has finished printing all the previous page of print data, the printing device generates a confirmation print completion notification for the latest received print completion query command and sends the confirmation print completion notification to the client to inform the client that the previous page of print data has been completely printed. Once the client knows that the previous page of print data has been completely printed, the client determines the target difference print data between the current page of print data and the previous page of print data from the current page of print data. Specifically, the method by which the client determines the target difference print data from the current page of print data can be found in the description of the relevant parts in the above embodiments, and will not be detailed here.

[0131] In some other embodiments, after the printing device has finished printing all the data on the previous page, it generates a confirmation instruction for the previous page's printing completion and sends this instruction to the client to inform the client that the previous page's printing data has been completely printed. Once the client is aware that the previous page's printing data has been completely printed, it determines the target difference printing data between the current page's printing data and the previous page's printing data within the current page's printing data.

[0132] S703: After a preset time has elapsed since the printing completion time of the target row of the printed data on the previous page, the target difference print data corresponding to the current page print data and the previous page print data is determined in the current page print data.

[0133] The target row print data may refer to a specific number of rows in the previous page print data. This specific number of rows can be set according to the actual application scenario, and this application embodiment does not impose any specific restrictions on it.

[0134] The preset duration can be set according to the actual application scenario, and this application embodiment does not impose specific limitations on it.

[0135] In some embodiments, after the client sends the previous page of print data to the printing device, the client can continuously send data comparison query commands to the printing device. After the printing device confirms that the printing completion time of the target row of print data in the previous page has elapsed for a preset period, the printing device generates a confirmation notification for the latest received data comparison query command. The printing device sends the confirmation notification to the client to inform the client that the previous page of print data can be compared, meaning the client can begin the operation of determining the target difference print data corresponding to the current page of print data and the previous page of print data. Specifically, the method by which the client determines the target difference print data in the current page of print data can be found in the description of the relevant parts in the above embodiments, and will not be detailed here.

[0136] In some other embodiments, after the printing device confirms that the printing completion time of the target row of the previous page's printed data has elapsed for a preset period, the printing device generates a confirmation instruction to start data comparison. The printing device then sends the confirmation instruction to the client to inform the client that data comparison can be started, meaning the client can begin the operation of determining the target difference printed data between the current page's printed data and the previous page's printed data.

[0137] S704, determine the data storage area for the target difference print data, store the target difference print data in the data storage area, determine the target print data based on the target difference print data, and perform print processing on the target print data.

[0138] For details on the implementation of S704, please refer to the description of the relevant parts in the implementation shown in Figure 2, which will not be elaborated here.

[0139] In the data printing method provided in this application embodiment, the printing device acquires and stores the previous page's print data. After the previous page's print data is completely printed, the client determines the target difference print data corresponding to the previous page's print data in the current page's print data. Alternatively, after a preset time has elapsed since the target row's print data in the previous page was completed, the client determines the target difference print data corresponding to the previous page's print data in the current page's print data. The printing device determines the data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. Therefore, by determining the target difference print data only after the previous page's print data is completely printed, the client can ensure that the target difference print data only needs to be sent to the printing device once for successful reception and storage by the printing device. By determining the target difference print data after a preset time has elapsed since the target row print data in the previous page was completed, the client can ensure that the target difference print data is prepared as quickly as possible and sent to the printing device as soon as possible. This reduces the waiting time for the printing device to receive the target difference print data, thereby optimizing the working efficiency of the printing device by reducing the amount of print data received and shortening the transmission time of the print data received by the printing device.

[0140] Please refer to Figure 8, which provides a flowchart of another data printing method according to an embodiment of this application.

[0141] Specifically, the data printing method includes:

[0142] S801, obtain the data to be printed corresponding to the target print job.

[0143] In some embodiments, step S801 can be performed by the client. After receiving the target print job initiated by the user, the client can obtain the print data of all pages selected for printing in the target print job and determine the print data of all pages as the print data to be printed.

[0144] S802, determine similar print data in the data to be printed, and determine the target printing order based on the similar print data.

[0145] In some embodiments, step S802 can be performed by the client. The client performs similar data detection on the data to be printed, identifies at least one set of similar page printing data in the data to be printed, sets a continuous printing order for the page printing data in each set of similar page printing data, and sets the printing order of the page printing data in the data to be printed other than the similar page printing data before the continuous printing order, or sets the printing order of the page printing data in the data to be printed other than the similar page printing data after the continuous printing order, thereby obtaining the target printing order. Wherein, the similarity between any two page printing data in each set of similar page printing data is greater than a preset similarity threshold.

[0146] S803, determine the initial printing order corresponding to the data to be printed, and determine the target printing order based on the initial printing order.

[0147] In some embodiments, step S803 can be performed by the client. The client obtains the initial print order corresponding to the data to be printed from the original file where the data to be printed is located. The initial print order can be understood as the page order of the data to be printed in the original file. The client can set the initial print order as the target print order.

[0148] S804 retrieves and stores the previous page's print data.

[0149] Specifically, the client can retrieve the previous page's print data according to the target printing order, and send the previous page's print order to the printing device so that the printing device can obtain the previous page's print data. The implementation method for the printing device to store the previous page's print data can be found in the description of the relevant parts in Figure 2, and will not be detailed here.

[0150] S805 retrieves the current page print data corresponding to the previous page print data according to the target print order.

[0151] In some embodiments, step S805 can be performed by the client. After sending the previous page print data to the printing device, the client can determine the first print sequence number of the previous page print data in the target printing order, determine the second print sequence number that is adjacent to and after the first print sequence number, and obtain the current page print data corresponding to the second print sequence number.

[0152] S806, determine the target difference print data between the current page print data and the previous page print data in the current page print data.

[0153] S807, determine the data storage area for the target difference print data, store the target difference print data in the data storage area, determine the target print data based on the target difference print data, and perform print processing on the target print data.

[0154] Specifically, the implementation methods of S806 and S807 can be found in the description of the relevant parts in the implementation shown in Figure 2, and will not be elaborated here.

[0155] In the data printing method provided in this application embodiment, the client obtains the data to be printed corresponding to the target printing task, determines similar printing data in the data to be printed, and determines the target printing order based on the similar printing data; alternatively, the client determines the initial printing order corresponding to the data to be printed and determines the target printing order based on the initial printing order. The printing device obtains and stores the previous page printing data. The client obtains the current page printing data corresponding to the previous page printing data according to the target printing order, and determines the target difference printing data corresponding to the current page printing data and the previous page printing data in the current page printing data. The printing device determines the data storage area for the target difference printing data, stores the target difference printing data in the data storage area, determines the target printing data based on the target difference printing data, and performs printing processing on the target printing data. Therefore, by determining the target printing order through similar printing data, the client can optimize the printing order of the data to be printed, and thus the client sends the printing data to the printing device according to the optimized printing order, thereby improving the printing efficiency of the printing device.

[0156] The data printing apparatus provided in the embodiments of this application will now be described in detail with reference to FIG. 9.

[0172] Optionally, the first printing processing unit is specifically used for:

[0173] In the target difference print data, at least one line of difference print data and the corresponding line number identifier are determined.

[0189] The data printing apparatus provided in this application embodiment acquires and stores the previous page's print data. It then determines the target difference print data corresponding to the previous page's print data within the current page's print data, identifies a data storage area for the target difference print data, stores the target difference print data in the data storage area, determines the target print data based on the target difference print data, and performs printing processing on the target print data. Therefore, by determining the target difference print data corresponding to adjacent pages' print data, the amount of print data acquired by the printing device during the printing process can be reduced. This avoids the problem of frequent pauses and waiting for print data during a single printing process, enabling the printing device to print continuously and stably, thus improving the printing device's working efficiency.
