[0053] Example 1

[0054] like Figure 1 As shown, the image printing method based on data transmission verification provided in Embodiment 1 of the present invention includes:

[0055] S1: Receive the file data of the document to be printed;

[0056] Specifically, the file data is PRN data that the printer can print after processing by the RIP software; the PRN data is file data in PRN format that the printer can print. Taking an image file as an example, the RIP software performs image halftone processing on the image to be printed, converting the graphic file into PRN data that the printer can recognize. When processing a file to be printed, the RIP software includes multiple processing steps to obtain multiple PRN data packets. The total data volume of all PRN data packets is equal to the file data volume of the file to be printed, which can realize simultaneous processing, verification, and printing, reducing the waiting time of each process. The file data includes the file type and specific file content of the file to be printed. This invention uses PRN format data as an example, but other formats of data can also be implemented according to the method of this invention. This invention does not limit these, and all variations in these file data formats are within the scope of protection of this invention.

[0057] Please see Figure 1-1 In a local area network printing system, there are at least one RIP software, one print control software, and at least one printer. Each RIP software performs network processing on the document to be printed, generates corresponding PRN data, and transmits the PRN data to the print control software. The print control software assigns the corresponding printer to each PRN data for printing according to the actual printing situation. The actual printing situation includes print requests from the RIP end or feedback information from the printer terminal.

[0058] S2: Determine the amount of received file data. When the amount of data reaches a file data amount threshold, establish a print job for the file to be printed. Specifically, the file to be printed is rasterized by RIP (Routing Information Protocol, software or hardware card in a typesetting system that interprets PostScript encoding as a bitmap image) software to obtain the PRN data that the printer can print, and send it to the print control software. The print control software starts receiving file data. Only when the amount of received file data reaches a certain value will a print job corresponding to the file to be printed be established. For example, if the PRN data received by the print control software is equal to the data of 1 Pass printing, a print job is established for the PRN data corresponding to this 1 Pass. Furthermore, in order to ensure print quality, the PRN data of a complete print job is divided into multiple PRN sub-data. A print job is divided into a start stage, a stable stage, and an end stage. The amount of PRN sub-data in the start stage and the end stage is less than the amount of PRN sub-data in the stable stage. This can improve the print quality of the print equipment's adaptive stage in the start stage, and at the same time, it can avoid large-area image abnormalities caused by excessively long closing data in the end stage, thus ensuring the quality of the printed image.

[0059] S3: Verify the received file data and obtain a print command that matches the verification result;

[0060] Specifically, when the print control software starts receiving file data, it simultaneously begins to verify the received file data to see if its file type is one that the printer can print. If the file type meets the printing requirements, the received file data is then verified for integrity using the same encryption method. Specifically, the file is encrypted at the sending end to obtain a first verification code; at the receiving end, the received file is encrypted using the same encryption method, and a second verification code is obtained after reception. If the first and second verification codes are the same, the received file data is complete, and a valid print command is generated; otherwise, an invalid print command is generated, and the file data needs to be resent.

[0061] S4: Execute the printing task according to the printing instructions.

[0062] Specifically, the printing instructions include those for valid files with normal data and those for invalid files with abnormal data.

[0063] Preferably, in step S3, the file data verification of the printed file includes checking for missing files, corrupted files, and files infected with viruses.

[0064] Specifically, abnormal file data includes situations where the file type to be printed is not a type that the printer can print, as well as situations where the file data itself is missing, corrupted, or contains viruses.

[0065] The image printing method based on data transmission verification in Embodiment 1 of this invention performs synchronous verification of the received file data when it is received. Simultaneously, a print job is created based on the amount of received file data, and a corresponding print instruction is generated based on the file data verification result. The print job, created based on the file data matching the print instruction, is then executed. The print instruction includes options to print the print job or not to print it. This invention can verify the file type and integrity of the file to be printed, reducing the error rate during the printing stage and improving printing efficiency.

[0066] In one embodiment, S2 includes:

[0067] S21: Get the current printing stage of the print job;

[0068] Specifically, a complete print job involves a large amount of data. If the receiving end only starts printing after receiving all the data, it will inevitably require a lot of data transmission time and have a low fault tolerance rate, which is not conducive to improving printing efficiency and quality. This application divides the printing stage of a print job into a start stage, a stable stage, and an end stage. The start stage can be regarded as the adaptive stage of the printing device to the current print job, that is, the stage of continuously optimizing the output image quality. The stable stage is the stage where the quality of the current print job is in a small fluctuation stage and meets the quality requirements. The end stage is the stage where the current print job is coming to an end. The final stage is the stage where image abnormalities are likely to occur, such as ink accumulation, image overlap, and other problems.

[0069] S22: If the current printing stage is the start stage or the end stage, the file data currently being transmitted is split into multiple file sub-data during the transmission process based on the file data volume threshold, resulting in multiple PRN data packets;

[0070] Specifically, the file data threshold is generally a percentage of the current file data volume, such as 5%, 10%, 20%, etc. If the current printing stage is the start or end stage, during the current file data transmission process, when the received data volume reaches the file data threshold, a PRN task is established, and the PRN task is directly converted into a PRN data packet to obtain a printable PRN data packet. Then, the remaining data volume of the current file data continues to be received, and the above steps are repeated until the current stage ends, resulting in multiple PRN data packets. If the remaining data volume of the current file data is less than the data volume threshold, blank data is filled in or it is directly used as a PRN data packet. This can prevent a large area of ​​abnormal image region from appearing during the adaptive process or the end process due to the large data volume of a single PRN data packet, thus ensuring image quality.

[0071] S23: If the current printing stage is a stable stage, when the amount of the received current file data reaches the file data amount threshold, a corresponding PRN task is established and transmission continues to obtain a PRN data packet;

[0072] Specifically, if the current printing stage is a stable stage, when the amount of data received from the current file reaches the data volume threshold, a corresponding PRN task is established. After the PRN task is established, the remaining amount of data from the current file continues to be received on that PRN task until the data from the current file is completely received, and a PRN data packet is generated. This can reduce the frequency of receiving data packets in the stable stage and ensure that most areas of the image belong to the same printing environment.

[0073] S24: Repeat steps S21 to S23 to create print jobs corresponding to each PRN data packet received continuously, thereby forming the print job of the document to be printed.

[0074] Specifically, after each PRN task is converted into a PRN data packet, the control software creates a print job for that PRN data packet. Once all the file data of the file to be printed has been converted into the corresponding PRN data packets, the print jobs corresponding to all the PRN data packets together form the print job for that file.

[0075] In one embodiment, such as Figure 3 As shown, S3 includes:

[0076] S301: Obtain the target file format and file tag of the file data that are recognizable by the printing device;

[0077] Specifically, it obtains the file format of the target file that the printer can print. The printer can only print PRN and PRT files. JPG and BMP files need to be processed by the Ritu software to generate PRN files before they can be recognized by the printer. It cannot directly recognize JPG, BMP, PDF or DOC files. It also obtains the file tags of the file data, which include the file type information and file size information of the file to be printed.

[0078] S302: Based on the file format information in the file label and the target file format, verify the consistency of the file type of the file to be printed, and obtain the consistency verification result of the file type of the file to be printed;

[0079] Specifically, the print control software determines whether the file to be printed is a file type that the printer can recognize based on the file type information in the file label, such as whether the file is a PRN file, a PRT file, or an image file in JPG or BMP format that can be converted to a PRN file.

[0080] S303: Generate the print command based on the consistency verification result.

[0081] Specifically, if the file format of the document to be printed is one that the printer can recognize, such as a PRN file, PRT file, or an image file in JPG or BMP format that can be converted to a PRN file, a print command is generated to execute the print job. Based on this print command, the printer is controlled to print according to the received PRN data. If the file format of the document to be printed is not one that the printer can recognize, such as a PDF or DOC document file, a print command is generated not to execute the print job. Based on this print command, the created print job can be deleted or marked to prevent the printer from printing the job and causing printing errors.

[0082] In one embodiment, such as Figure 4 As shown, if the file type of the document to be printed is a target file format that the printing device can recognize, further step S3 includes:

[0083] S311: Generate a new verification tag for the received file data in the same manner as the file tag corresponding to the generated file data;

[0084] Specifically, after performing image screening on the file to be printed, the RITX software obtains file data, i.e., PRN data. At the same time, a file tag is generated based on the file data, which can be understood as encrypting the file data. After receiving and verifying the file data, the print control software generates a new tag in the same way as generating the file tag. This can be understood as the print control software generating a new tag in the same encryption method when decoding the file data. This new tag is called the verification tag.

[0085] S312: Based on the file tag and the verification tag, verify the integrity of the file data of the file to be printed, and obtain the integrity verification result of the file data;

[0086] Specifically, since the verification tag and the file tag are generated in the same way, the verification tag and the file tag are compared. If the verification tag and the file tag are the same, it means that the file data after verification is the same as the file data obtained after the file to be printed is screened, that is, there is no file corruption, missing and / or virus; otherwise, the file data after verification is incomplete.

[0087] S313: Generate the print instruction based on the integrity verification result.

[0088] Specifically, if the verification result indicates that the file data is complete, a print command is generated to indicate that the print job can be printed. Based on this print command, the printer is controlled to print according to the received PRN data. If the verification result indicates that the file data is incomplete, a print command is generated to indicate that the print job cannot be printed. Based on this print command, the established print job can be deleted or marked to prevent the printer from printing the print job and causing printing errors.

[0089] In one embodiment, such as Figure 5 As shown, an image printing method based on data transmission verification is provided;

[0090] S3 includes verifying the duplication of file data in the document to be printed.

[0091] S321: Generate verification tags for each of the verified file data to obtain a verification tag group;

[0092] Specifically, the print control software generates a verification tag after verifying the file data of each file to be printed, and combines the verification tags of all the files to be printed that have completed verification into a verification tag group.

[0093] S322: Compare the verification tag of the newly received and verified file data with the verification tags in the verification tag group to verify the duplication of the file data of the file to be printed, and obtain the duplication verification result of the current file data;

[0094] Specifically, each time the print control software generates a new check tag, it needs to compare the new check tag with the check tags in the check tag group. If there is no check tag in the check tag group that matches the new check tag, the new check tag is added to the check tag group to complete the duplicate check of the file data, and the result is that the file data is not duplicated. If there is already a check tag in the check tag group that matches the new check tag, the new check tag is not added to the check tag group, and the result is that the file data is duplicated.

[0095] S323: Generate the print instruction based on the repeatability check result.

[0096] Specifically, if the verification result indicates that the file data is not duplicate data, then a print command is generated indicating that the print job can be printed. Based on this print command, the printer is controlled to print according to the received PRN data. If the verification result indicates that the file data is duplicate data, then a print command is generated indicating that the print job cannot be printed. Based on this print command, the established print job can be deleted or marked to prevent the printer from printing the print job and causing printing errors.

[0097] It should be noted that: the repeatability check includes the check of the PRN data corresponding to the entire file to be printed, as well as the check of each PRN data packet of the file to be printed sent by the RIP software to the print control software each time; this invention mainly targets the check of each PRN data packet of the file to be printed.

[0098] In one embodiment, such as Figure 6 As shown, an image printing method based on data transmission verification is provided;

[0099] It also includes, before S1;

[0100] S11: At the document processing terminal to be printed, broadcast according to the broadcast protocol;

[0101] Specifically, after completing the halftone processing of the image of the document to be printed, the Ritu software broadcasts it to the local area network (LAN) or wide area network (WAN) through a predetermined protocol, searching for print control software within the LAN or WAN.

[0102] S12: Send the receiving address of the file data receiving end to the address corresponding to the received broadcast;

[0103] Specifically, after receiving the broadcast, the print control software responds and sends its address information, specifically its IP address and port, to the Ritu software according to a predetermined protocol.

[0104] S13: Send the file data to the receiving address according to the receiving address.

[0105] Specifically, after receiving the address information from the print control software, the Ritu software sends file data to that address, thus initiating the file data transfer.

[0106] It should be noted that the network includes multiple Ritu software programs and multiple print control software programs. The information fed back to the Ritu software by the print control software includes the print control software's address information, i.e., IP address, and the current working status of the printer corresponding to the print control software, i.e., the number of print jobs, the printer's working time, and the next downtime.

[0107] The image printing method based on data transmission verification in Embodiment 1 of this invention performs synchronous verification of the received file data when it is received. Simultaneously, a print job is created based on the amount of received file data, and a corresponding print instruction is generated based on the file data verification result. The print job, created based on the file data matching the print instruction, is then executed. The print instruction includes options to print the print job or not to print it. This invention can verify the file type and integrity of the file to be printed, reducing the error rate during the printing stage and improving printing efficiency.
