[0038] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0039] Figure 1 This is a schematic flowchart of the printing control method provided by the embodiments of the present invention. This method can be executed by the printing control device provided by the embodiments of the present invention, and the device can be implemented in software and / or hardware. In a specific embodiment, the device is applied to a protocol conversion device, and the protocol conversion device is installed on a host computer, and the host computer is connected to a printer. The following embodiments will be described by taking the device integrated in an electronic device as an example. Refer to Figure 1 , and the method may specifically include the following steps:

[0040] S110. Receive a printing task sent by the host computer;

[0041] Exemplarily, the protocol conversion device can be a device implemented in software and / or hardware and having the function of converting the printing data in the printing task. The situation where the agreements followed by the communication between the host computer and the printer are inconsistent can be resolved by converting the printing data in the printing task. Among them, multiple printing protocols are stored in the protocol conversion device, and the printing protocols stored in the protocol conversion device are used to parse the data of the printing task received from the host computer to determine the printing data in the printing task. The host computer can be a computer that directly sends a printing command, and determines the printing task that the printer needs to print by displaying various information on the screen. Among them, the printing task can be a data packet containing the data that the printer needs to print, and the packaging method of the printing task can be determined according to the communication protocol between the host computer and the printer. Different communication protocols can correspond to different packaging methods.

[0042] In specific implementation, on the host computer or the printer installed with the protocol conversion device, the protocol conversion device receives the printing task sent by the host computer to the printer, and analyzes the printing task to obtain the data characteristics of the printing task, so as to confirm the data parsing protocol corresponding to the printing task according to the data characteristics of the printing task. Among them, the connection method between the protocol conversion device and the host computer can adopt network connection, serial port connection, and Bluetooth interactive access method, or can be integrated into the host computer; among them, the connection method between the protocol conversion device and the printer can adopt network connection, serial port connection, wire connection, and Bluetooth and other connection methods.

[0043] S120. Analyze the printing task to obtain the data characteristics of the printing task;

[0044] In specific implementation, the print data in the print task is encapsulated and packed in the form of instruction sets. Among them, the instruction sets corresponding to each preset protocol are different or have differences, and the instruction sets corresponding to each preset protocol have corresponding data characteristics. For example, the ESC instruction set, the TSPL instruction set, and the CPCL instruction set. Among them, the data characteristics can be that the instruction set contains general data symbols, special data combination rules, and print control languages, etc. Determine the data characteristics of the print task by analyzing the data language, data symbols, and data combination rules in the instruction set of the print task, so as to determine the data parsing protocol corresponding to the print task according to the data characteristics of the print task and obtain the print data.

[0045] S130. Determine the data parsing protocol corresponding to the print task according to the data characteristics, and parse the print task according to the data parsing protocol to obtain the print data;

[0046] In specific implementation, the data parsing protocol corresponding to the print task can be the print protocol used when the host computer generates the print task. This print protocol is used to encapsulate the print data into packets, and the relevant rules of the print protocol can also be used to parse the print task to obtain the print data in the print task, so as to perform data conversion on the print data to form a print instruction that the printer can recognize, and complete the print task sent by the host computer according to the print instruction. Match the print protocol that conforms to the data characteristics from each preset protocol according to the data characteristics of the print task. When the data parsing protocol corresponding to the print task is matched from each preset protocol according to the data characteristics of the print task, use this data parsing protocol to parse the instructions in the print task to obtain the print data, where the print data contains the content that the host computer needs to print.

[0047] S140. Convert the print data into bitmap data, and send a print instruction to the printer based on the bitmap data.

[0048] In specific implementation, the bitmap data can be display data that displays the print data in the form of bitmap and vector graphics. The display data can be a pixel group, and each pixel in the array represents a point in the picture, that is, a point sample. Use the data parsing protocol to parse the instruction set in the print task to obtain the print data, and perform dot matrix conversion on the print data to obtain the bitmap data corresponding to the print data. In fact, perform image conversion on the print data to obtain the bitmap data. The bitmap data is stored using pixels as memory units, that is, the smallest memory unit can be used to mark a number, and the storage space of the data can be reduced through the mapping rule to achieve the purpose of increasing the storage capacity. The bitmap data, as the image-converted data, can be converted through the print protocol of the printer to generate a print instruction that the printer can execute.

[0049] In an embodiment of the present invention, a printing task sent by a host computer is received; the data characteristics of the printing task are analyzed; a data parsing protocol corresponding to the printing task is determined according to the data characteristics, and the printing task is parsed according to the data parsing protocol to obtain printing data; the printing data is converted into bitmap data, and a printing instruction is sent to the printer based on the bitmap data. That is, in the embodiment of the present invention, a data parsing protocol is determined through the data characteristics of the printing task, printing data is obtained according to the data parsing protocol for data conversion to form bitmap data, and the bitmap data is used as intermediate data for storage and generation of printing instructions. Different protocols corresponding to printing tasks can be printed by the printer by means of data conversion, the compatibility of multiple protocols of the printer is enhanced, the reuse rate of the device is improved, the device cost is reduced, and in addition, the data storage capacity of the device can be improved by using the bitmap data as intermediate data.

[0050] The printing control method provided by the embodiment of the present invention is further described below. As Figure 2 shown, the method may specifically include the following steps:

[0051] S210. Receive a printing task sent by a host computer;

[0052] S220. Analyze the printing task to obtain the data characteristics of the printing task;

[0053] In a specific implementation, the printing data in the printing task is encapsulated and packed in the form of an instruction set. Among them, the instruction sets corresponding to each preset protocol are different or have differences, and each preset protocol corresponds to an instruction set with corresponding data characteristics. For example, the ESC instruction set, the TSPL instruction set, and the CPCL instruction set. Among them, the data characteristics may be that the instruction set contains general data symbols, special data combination rules, and printing control languages, etc. The data characteristics of the printing task are determined by analyzing the data language, data symbols, and data combination rules in the printing task, so as to determine the data parsing protocol corresponding to the printing task according to the data characteristics of the printing task and obtain the printing data.

[0054] For example: The printing task sent by the ESC instruction set contains data characteristics of instruction combinations such as 0x1b 0x40, 0x1b 0x4a, 0x1b 0x64, and 0x1d 0x76. The printing task sent by the TSPL instruction set contains data characteristics of instruction combinations such as!, T, PRINT, etc. The printing task sent by CPCL contains data characteristics of instruction combinations such as SIZE, PRINT, etc.

[0055] S230. Determine a preset matching time according to each preset protocol, and determine whether the data characteristics match the characteristics of the current protocol within the preset matching time;

[0056] Exemplarily, the preset matching time can be the time required for the data characteristics of the printing task preset according to actual requirements and experimental data to match the data characteristics of the instruction set corresponding to each preset protocol. It can be the unit time preset according to experimental data, that is, the matching time of each preset protocol is the same. It can also be the preset matching time set corresponding to each preset protocol differently, that is, the preset times of the data characteristics of the instruction set corresponding to each preset protocol are different. The current protocol can be the printing protocol that is currently performing feature matching during the data feature matching process, that is, any one of the preset protocols. During the data feature matching process, the preset protocols can determine the matching order according to certain rules, and then perform matching on each preset protocol one by one. Among them, the feature of the current protocol can be the data characteristics of the instruction set of the current protocol. Among them, it can be sorted from large to small according to the number of successful matches of each preset protocol, or when the preset matching times are inconsistent, it can be sorted from small to large according to the length of the preset matching time, so as to reduce the matching time.

[0057] In specific implementation, to determine the preset matching time corresponding to each preset protocol during the data feature matching process according to each preset protocol, it can be the unit time preset according to experimental data, or the preset matching time can be set corresponding to each preset protocol differently. Perform sequential matching according to the preset matching time corresponding to each preset protocol and the matching order corresponding to each preset protocol. Each preset protocol performs data feature matching to determine whether the data characteristics match the features of the current protocol within the preset matching time. When the data characteristics do not match the data characteristics of the instruction set of the current protocol, that is, the data characteristics are inconsistent with the data characteristics of the instruction set of the current protocol, or when it cannot be determined whether the data characteristics are consistent with the data characteristics of the instruction set of the current protocol within the preset matching time, it is determined that the data characteristics do not match the data characteristics of the instruction set of the current protocol.

[0058] S240. When the data characteristics do not match the characteristics of the current protocol, sequentially execute the matching of the data characteristics with the next protocol until the data parsing protocol corresponding to the printing task is matched from each preset protocol;

[0059] In a specific implementation, the next protocol can be the printing protocol to be matched next after the current protocol matching ends during the data feature matching process, that is, the printing protocol after the current protocol in the sorting. Sequentially match according to the preset matching time corresponding to each preset protocol and the matching order corresponding to each preset protocol. Each preset protocol performs data feature matching to determine whether the data features match the features of the current protocol within the preset matching time. When the data features do not match the data features of the instruction set of the current protocol, that is, when the data features are inconsistent with the data features of the instruction set of the current protocol, then sequentially execute the matching of the data features with the next protocol until the data parsing protocol corresponding to the number of printed people is matched from each preset protocol. Additionally, when it is impossible to determine whether the data features match the data features of the instruction set of the current protocol and the preset matching time has arrived, then determine that the data features do not match the data features of the instruction set of the current protocol, and then sequentially execute the matching of the data features with the next protocol until the data parsing protocol corresponding to the number of printed people is matched from each preset protocol. For example, set the preset matching time to a consistent time of 3 seconds, determine whether the data features match the data features of the instruction set of the current protocol within 3 seconds. When the data features do not match the data features of the instruction set of the current protocol within 3 seconds, then determine that the data features do not match the data features of the instruction set of the current protocol, and sequentially execute the matching of the data features with the next protocol within the next 3 seconds until the data parsing protocol corresponding to the number of printed people is matched from each preset protocol.

[0060] S250. Parse the print task according to the data parsing protocol to obtain print data, where each preset protocol is stored in the protocol conversion device;

[0061] In a specific implementation, match the print protocol that conforms to the data features of the print task from each preset protocol according to the data features of the print task, and match according to the data language, data symbols, and data combination rules of the instruction set corresponding to each preset protocol and the data features of the print task. When it is determined that the data features of the instruction set corresponding to a print protocol are consistent with the data features of the print task from each preset protocol, then the data features of the instruction set corresponding to the print protocol match the data features of the print task, and use this print protocol as the data parsing protocol corresponding to the print task, and use this data parsing protocol to parse the instruction set in the print task to obtain print data. Among them, each preset protocol is stored in the protocol conversion device and is used to determine the data parsing protocol through data feature matching.

[0062] S260. Convert the print data into bitmap data, and send a print instruction to the printer based on the bitmap data.

[0063] Further, converting the print data into bitmap data includes:

[0064] Determine the content of the print data, and perform bitmap mapping on the content of the print data to obtain bitmap information;

[0065] Format the bitmap information according to the general data format to obtain bitmap data.

[0066] In a specific implementation, the general data format can be an image file format, for example, the BMP file storage format. Parse the instruction set in the print task using a data parsing protocol to obtain the print data, determine the content of the print data, perform bitmap mapping on the content of the print data, determine the position information of each dot in the bitmap data, and format the bitmap information according to the general data format to obtain bitmap data or a bitmap file, so as to combine the print data and the print protocol through image scanning to generate a print instruction.

[0067] Further, send a print instruction to the printer based on the bitmap data, including:

[0068] Obtain the print protocol from the printer, and generate a print instruction according to the bitmap data and the print protocol;

[0069] Send the print instruction to the printer so that the printer can complete the print task according to the print instruction.

[0070] In a specific implementation, utilize the communication connection between the protocol conversion device and the printer to obtain the print protocol of the printer, combine the print data and the print protocol through image scanning to generate a print instruction, send the print instruction to the printer, and the printer completes the print task according to the received print instruction.

[0071] Further, after sending the print instruction to the printer so that the printer can complete the print task according to the print instruction, it further includes:

[0072] Receive a new protocol, and update the new protocol to the preset protocol library.

[0073] In a specific implementation, after each time the printer instruction is sent to the printer, it is necessary to receive the new protocol through the network. It can be the server connected to the network for data update to receive the new protocol, or the protocol conversion device for data update to receive the new protocol, update the new protocol to the preset protocol library, and re-determine the preset matching time and the order of data feature matching of each preset protocol in the preset protocol library, so as to perform data feature matching on the received new print task.

[0074] In an embodiment of the present invention, a printing task sent by a host computer is received; data characteristics of the printing task are analyzed; a data parsing protocol corresponding to the printing task is determined according to the data characteristics, and the printing task is parsed according to the data parsing protocol to obtain printing data; the printing data is converted into bitmap data, and a printing instruction is sent to a printer based on the bitmap data. That is, in the embodiment of the present invention, the data parsing protocol is determined according to the data characteristics of the printing task, the printing data is obtained according to the data parsing protocol for data conversion to form bitmap data, and the bitmap data is used as intermediate data for storage and generation of a printing instruction. Different printing tasks corresponding to different protocols can be printed by the printer by means of data conversion, the compatibility of multiple protocols of the printer is enhanced, the reuse rate of the device is increased, the device cost is reduced, and in addition, the data storage capacity of the device can be improved by using the bitmap data as intermediate data.
