[0043] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0045] In the present application, the term "include" and its variations may refer to non-restrictive inclusion; the term "or" and its variations may refer to "and / or". The terms "first", "second", etc. in the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In the present application, "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0046] The following describes and explains the terms and concepts involved in the embodiments of the present application:

[0047] Image forming equipment: For example, printers, copiers, scanners and fax machines, have greatly improved the efficiency of data processing and output.

[0048] Electronic device: may be a device that controls an image forming device to perform an image forming operation, for example, may be a computer, a mobile phone, or a tablet computer.

[0049] Driver: As a bridge between the electronic device and the image forming device, it can translate the commands issued by the electronic device into commands that the image forming device can understand, thereby ensuring that the image forming device can accurately execute various commands. Optionally, the driver can be on the image forming device or on the electronic device.

[0050] Print command: for example, may include one or more of PCL command, PJL command, Graphics Device Interface (GDI) command or Print Language (PL) command.

[0051] PCL command: It is a command about page description language, which can specify how to present various elements on the page, including the layout and format of text and images, and how to present the printed content on the page, such as the font, size, color of the text, pixel data of the image, etc. PCL command can ensure that the content printed by the printer is consistent with the content displayed on the screen of the electronic device, so as to achieve high-quality printing effect.

[0052] PJL command: is a control language command, which is mainly used to manage the overall process of printing jobs. PJL commands can not only include direct control instructions for printer hardware, such as starting printing, pausing printing, canceling printing, etc., but also provide settings for print job properties, such as printing speed, number of copies, printing resolution, etc.

[0053] Graphics Device Interface (GDI) commands: used to output document content such as text and images. The difference between GDI commands and PCL commands is that GDI is a command for rasterization, while PCL is a command for vectorization.

[0054] Print Language (PL) command: a set of commands that control the operation of the printer.

[0055] Similar to PCL commands and PJL commands, graphics device interface commands or commands formed by printing languages ​​can translate commands issued by electronic devices into commands that can be understood by image forming devices. Such commands can be collectively referred to as printing commands.

[0056] Print description file: A file that uses print commands to describe print information. The print information may include any one or more items such as print area, page settings, and print content.

[0057] Printer firmware: The software on the printer that is responsible for connecting the computer and printer hardware communication and control.

[0058] Taking a printer as an example, a printer driver is installed in the electronic device, which is used to generate a print description file when a user triggers a print task. The print description file includes: converting the computer's print task into commands that the printer can understand and execute, such as PCL commands and / or PJL commands, to convert the electronic device's print task into print commands that the printer can understand and execute.

[0059] The printer is provided with printer firmware for parsing the print description file sent by the electronic device, rendering and imaging the print command obtained by the parsing, and finally converting it into an electrical signal for controlling the laser scanning unit to form the print content.

[0060] In the process of generating a print description file by a driver, an error may occur in the electronic device, resulting in an erroneous print command in the print description file, for example, the generated print command does not meet the format requirements. The non-compliance with the format requirements mentioned here may include syntax errors and / or semantic errors. Among them, a syntax error may be that the generated print command does not meet the rules in structure; a semantic error may be that the generated print command has a logical error.

[0061] In this scenario, the printer firmware will parse the print description file and obtain an erroneous print command, resulting in an error page in the print result. The error page may include the current error reason, for example, as shown below:

[0062] PCL XL error:

[0063] Subsystem: KERNEL

[0064] Error: InsufficientMemory

[0065] Operator: BeginImage

[0066] Position: 1411

[0067] Therefore, currently, when an error occurs in the process of an electronic device generating a print description file through a driver, the user will not be able to use the printer normally before the problem is resolved, which affects office efficiency.

[0068] In view of this, the present application provides a print data repair method that can automatically detect and repair erroneous print commands in a print description file, thereby avoiding the problem of printing erroneous pages due to erroneous commands, which affects office efficiency.

[0069] The code corresponding to the print data repair method provided in the present application can be set in the driver or printer firmware, or in other programs independent of the driver or printer firmware, or it can be a newly added program specifically used to execute the repair method, etc.

[0070] It should be understood that when the program is set on an electronic device, the execution subject of the method can be the electronic device running the program. When the program is set on a printer, the execution subject of the method can be the printer running the program.

[0071] The following embodiments are all described by taking the electronic device as the execution subject and the code corresponding to the printing data repair method being set in the driver as an example.

[0072] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0073] Figure 1 The following is a flow chart of a printing data repair method provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0074] S101, obtaining a print description file and a rule file, wherein the print description file is used to describe print information through a preset print command, and the rule file is used to determine the format requirements of the preset print command.

[0075] The above-mentioned print description file may be generated by the electronic device through a driver based on a print task triggered by a user.

[0076] The rule file may include, for example, the format requirements of the preset print command. The format requirements may include, for example, any one or more of the start identifier, end symbol, action indication, keyword, and parameter validity of the preset print command. The action indication may indicate the specific operation to be performed by the preset print command; the keyword may specify the parameters of the specific operation.

[0077] Taking the PJL command as an example, its format requirement can be:

[0078] (1) Each individual PJL command begins with “@PJL”.

[0079] (2) Ends with "0x0D, 0x0A".

[0080] (3) “@PJL” is followed by “action”, for example, “SET” or “ENTER”.

[0081] (4) "Action" is followed by "keywords", for example, "USERNAME", "RENDERMODE", etc.

[0082] (5) The content after the “keyword” does not contain grammatical errors or semantic errors.

[0083] A preset printing command that satisfies (1)-(5) at the same time can be considered to meet the format requirements.

[0084] This embodiment does not limit the method for obtaining the rule file. For example, the rule file may be set in a driver program.

[0085] S102: If the print description file contains a first print command that does not meet the format requirement, repair the first print command to obtain a repaired print description file, wherein all print commands in the repaired print description file meet the format requirement.

[0086] By comparing the print command in the print description file with the rule file, it can be determined whether the print command in the print description file meets the format requirements. For the print command that does not meet the format requirements (referred to as the first print command in this application), the electronic device can repair it through the repair code in the driver, and the target repair method can include, for example, deleting the first print command, deleting illegal bytes in the first print command, replacing illegal bytes in the first print command with preset values, filling missing bytes in the first print command with preset values, and any one or more of the above.

[0087] It should be understood that the embodiments of the present application do not limit how to identify the print command from the above-mentioned print description file. For example, the print command can be identified from the above-mentioned print description file through the print protocol identification rule. The print protocol identification rule can be a separate rule file, or it can be included in the rule file for determining the format requirements of the preset print command, which is not limited.

[0088] The print protocol identification rule may include a specific beginning sequence and a specific ending sequence of the print command. Taking the PJL command as an example, its print protocol identification rule may be:

[0089] (1) Starts with the data “0x1B%-12345X@PJL”.

[0090] (2) Ends with the data “@PJL ENTER LANGUAGE”.

[0091] A command that satisfies both (1) and (2) printing protocol identification rules may be a PJL command.

[0092] It should be understood that the target repairing method adopted for repairing the first print command may be determined according to, for example, the type of the first print command and / or the reason why the first print command does not meet the format requirement.

[0093] The following first describes how to select a corresponding target repairing method according to the type of the first printing command.

[0094] The type of the print command may be a target function-related command of a non-graphic printing device or a target function-related command.

[0095] Optionally, the target function-related commands of the non-graphic printing device may be non-core function commands in the printing process, such as any one or more of the commands for user name and command for displaying printer status. Since the existence or non-existence of the target function-related commands of the non-graphic printing device does not affect the printed content, the target repair method of such commands may be, for example, a repair method of deleting the first printing command or deleting illegal bytes in the first printing command, so that the accuracy of the printed content can be guaranteed when the erroneous command is repaired.

[0096] For example, the PJL command for the user name (USERNAME) in the rule file is:

[0097] "@PJL SET USERNAME = link 0x0D0x0A", (link is set by the user and is not limited here)

[0098] In the print description file, the first print command, that is, the PJL command of the user name (USERNAME), is:

[0099] "@PJL SET USERNAME=link 0x0D0x0A 0x0D0x0A",

[0100] Since the first print command repeats 0x0D0x0A, the second 0x0D0x0A is an illegal byte. At this time, the first print command is wrong. If the first print command is used for printing, it may cause the problem of printing an error page. Since the first print command is a command related to the target function of the non-graphic printing device, the electronic device can control the driver to delete the first print command so that the printer outputs the print content. Alternatively, the illegal bytes in the first print command are deleted, that is, the second 0x0D0x0A illegal byte is deleted, so that the printer outputs the print content.

[0101] Optionally, the target function-related command may be a core function command in the printing process, such as a command for the number of copies to be printed, a command for the printing direction, or any one or more of the above. Deleting or deleting illegal bytes from the target function command may affect the printed output content. Therefore, the target function-related command repair method selects to replace the illegal bytes in the first print command with a preset value, or to fill the missing bytes in the first print command with a preset value.

[0102] For example, the PJL command for printing the number of copies (COPIES) in the rule file is:

[0103] "@PJL SET COPIES = 1 0x0D0x0A", (1 is the default value of this command, which is not limited here)

[0104] In the print description file, the first print command, that is, the PJL command for printing the number of copies (COPIES), is:

[0105] "@PJL SET COPIES=-5 0x0D0x0A",

[0106] Since the number of copies to be printed is usually an integer greater than or equal to 1, -5 in the above-mentioned first print command is an illegal byte in the first print command. If the first print command is used for printing, an error page may be printed. Since the first print command is a command related to the target function, deleting the first print command or deleting the illegal bytes in the first print command may cause a failure to print. Therefore, the preset value (also called the default value) corresponding to the first print command, i.e., 1, can be used to replace the illegal byte -5 in the first print command so that the printer can correctly output the print content.

[0107] Exemplarily, in the print description file, the first print command, that is, the PJL command for printing the number of copies (COPIES) is:

[0108] "@PJL SET COPIES=0x0D0x0A",

[0109] In the first print command, since the PJL command for the number of copies is missing bytes, if the first print command is used for printing, an error page may be printed. Since the first print command is a command related to the target function, deleting the first print command or deleting illegal bytes in the first print command may cause a situation where printing cannot be performed. Therefore, the preset value (also called the default value) corresponding to the first print command, i.e., 1, may be used to fill the missing bytes in the first print command so that the printer can correctly output the print content.

[0110] The embodiment of the present application can select a corresponding repair method according to the type of the first printing command, select a repair method of deleting or deleting illegal bytes when an error occurs in a command related to the target function of a non-graphic printing device, and select a repair method of replacing or filling with preset values ​​when an error occurs in a command related to the target function, thereby avoiding invalid repairs and improving repair efficiency.

[0111] The following describes how to select a corresponding repair method according to the reason why the first print command does not meet the format requirement.

[0112] Optionally, the reason why the first print command does not meet the format requirement may be that there is a syntax error or a semantic error. When a syntax error occurs in the first print command, a repair method of deleting the first print command or deleting illegal bytes in the first print command may be selected. When a semantic error occurs in the first print command, a preset value may be used to replace the illegal bytes in the first print command, or a preset value may be used to fill the missing bytes in the first print command.

[0113] Exemplarily, in the print description file, the PJL command of the first print command regarding the user name (USERNAME) is:

[0114] "@PJL SET USERNAME=link 0x0D0x0A 0x0D0x0A",

[0115] Since the first print command repeats 0x0D0x0A, the second 0x0D0x0A is an illegal byte, and the first print command is a syntax error. The existence or non-existence of a command with a syntax error does not affect the printed content. Therefore, the target repair method of such a command can be, for example, a repair method of deleting the first print command or deleting the illegal bytes in the first print command, so that the accuracy of the printed content can be guaranteed when the erroneous command is repaired. Therefore, the electronic device can control the driver to delete the first print command so that the printer outputs the printed content. Alternatively, the illegal bytes in the first print command are deleted, that is, the second illegal byte 0x0D0x0A is deleted, so that the printer correctly outputs the printed content.

[0116] Exemplarily, in the print description file, the PJL command of the first print command regarding the number of copies (COPIES) is:

[0117] "@PJL SET COPIES=-5 0x0D0x0A",

[0118] Since the number of copies to be printed is usually an integer greater than or equal to 1, -5 in the first print command is an illegal byte in the first print command, and a semantic error occurs in the first print command. Since the first print command is a semantic error, deleting the first print command or deleting the illegal byte in the first print command may cause a situation where printing cannot be performed. Therefore, a preset value (also called a default value) corresponding to the first print command, i.e., 1, may be used to replace the illegal byte -5 in the first print command, so that the printer can correctly output the print content.

[0119] Similarly, if the PJL command regarding the number of copies to be printed is missing bytes, it is also a semantic error. Since the first print command is a command related to the target function, deleting the first print command or deleting the illegal bytes in the first print command may cause printing failure. Therefore, the preset value corresponding to the first print command (also called the default value), that is, 1, can be used to fill the missing bytes in the first print command so that the printer can correctly output the print content.

[0120] In addition, a corresponding repair method may be selected according to the type of the first print command and the reason why the first print command does not meet the format requirement.

[0121] Still taking the PJL command of the first print command about the user name (USERNAME) in the print description file as an example:

[0122] "@PJL SET USERNAME=link 0x0D0x0A 0x0D0x0A",

[0123] The first print command repeats 0x0D0x0A, resulting in the second 0x0D0x0A being an illegal byte. The first print command firstly belongs to a command related to the target function of the non-graphic printing device, and secondly, the error of the first print command is a syntax error. The existence or non-existence of a command with a syntax error does not affect the print content. Therefore, the first print command can be deleted to enable the printer to output the print content. Alternatively, the illegal bytes in the first print command are deleted, that is, the second 0x0D0x0A illegal bytes are deleted to enable the printer to correctly output the print content.

[0124] On the basis of selecting a corresponding repair method according to the type of the first print command and / or the reason why the first print does not meet the format requirements, the embodiment of the present application can also display the error information and the repair method to the user, and the user can choose whether to repair the first print command. Exemplarily, the electronic device control driver can display the error information and the repair method to the user in the form of a pop-up window, and provide the user with an option of whether to perform the repair, and can perform the repair in response to the user selecting the option to perform the repair.

[0125] Optionally, the embodiment of the present application can also display the error information and the repair method to the user after the automatic repair is completed or after printing, so that the user can understand the error information and the automatic repair method in time and improve the user experience.

[0126] The print data repair method provided in the embodiment of the present application can locate the print commands that do not meet the format requirements in the print description file according to the rule file, and automatically repair them, thereby avoiding the situation where error pages appear in printing due to erroneous print commands.

[0127] The above-mentioned target repairing method may also be located in a rule file used to determine the format requirements of a preset print command, that is, the rule file is not only used to determine whether the print command meets the format requirements, but can also be further used to determine the repairing method of the print command.

[0128] In an embodiment of the present application, the electronic device control driver can accurately identify the print command based on the rule file, and determine whether the print command is incorrect based on the rule file. The incorrect print command can also be quickly repaired according to the mapping relationship in the rule file, thereby improving the accuracy of repairing erroneous commands, reducing the time for manual inspection and repair of print commands, and improving the efficiency of printing tasks.

[0129] The above printing data repair method can be regarded as a function of the electronic device controlling the driver program. The printing data repair method can be an optional mode of the driver program, that is, it can be turned on or off based on the needs of the user.

[0130] Specifically, Figure 2 A schematic diagram of a user interaction interface provided in an embodiment of the present application. Figure 2 As shown, the print data repair method can be used as an option in the driver user interface for the user to operate. When the user selects the automatic repair mode option, the electronic device will first execute the above-mentioned method after running the driver to generate the print description file. Figure 1 After the repair method is shown, the repaired print description file is sent to the printer to perform the printing operation. After the repair is completed, the user can uncheck this option to turn off the repair mode. After the electronic device generates the print description file, it will directly send it to the printer to perform the printing operation without executing Figure 1 The fix shown here makes the printer run faster.

[0131] The embodiment of the present application provides the user with an option in the user interaction interface of the driver to enable the user to choose to turn on or off the repair mode. The user can use this option to choose whether to enter the repair mode according to his or her own needs. This method meets the personalized needs of the user, increases the operating speed of the printer after turning off the repair mode, and enhances the user experience.

[0132] It should be understood that the repair process described above only repairs the print description file in the current printing process. The erroneous print description file is usually caused by the driver. Furthermore, the embodiment of the present application can also use the description information of the first print command as the patch information of the print driver to avoid the subsequent operation of the driver to generate a print description file containing this erroneous print command.

[0133] Optionally, the description information of the first print command may be a “keyword” of the first print command. The description information of the first print command may be used as patch information of the print driver.

[0134] Exemplarily, the PJL command of the first print command in the above print description file regarding the user name (USERNAME) is:

[0135] "@PJL SET USERNAME=link 0x0D0x0A 0x0D0x0A",

[0136] Since the first print command repeats 0x0D0x0A, the second 0x0D0x0A is an illegal byte, and the first print command is wrong. For this wrong first print command, the "keyword" of the PJL command about the user name (USERNAME), that is, USERNAME, can be used as patch information.

[0137] Subsequently, when running the driver to generate a print description file, the patch information can be traversed, so that based on the description information of the first print command included in the patch information, the generation of the first print command can be skipped. Alternatively, the target repair method corresponding to the first print command can be used to generate and repair the first print command, so that the generated print description file does not contain the first print command that does not meet the format requirements.

[0138] The patch information may be stored in a separate file or in the aforementioned rule file. Taking the PJL command as an example, the rule file may be as shown in the following Table 1:

[0139] Table 1

[0140]

[0141] Furthermore, the patch information can also be synchronized to the server, which can be the server corresponding to the printer device manufacturer. By synchronizing the patch information to the server, the printer device manufacturer can analyze the command with the error, so as to completely solve the related problems in the subsequent driver update. That is, the electronic device can receive the print driver updated based on the patch information sent by the server. The print driver updated based on the patch information solves the above problem, so that the next time the required print description file is generated, the situation of generating the first print command with the error will no longer occur.

[0142] In the prior art, when an error page appears during printing, the user can only rely on contacting the printer device manufacturer to visit the manufacturer to check the job data that caused the problem in order to analyze the cause of the error, which results in a long time and low efficiency in repairing the driver. Furthermore, if the job data involves the user's confidential information and cannot be disclosed to the device manufacturer, the problem will be difficult to solve.

[0143] The embodiment of the present application reports patch information to the server, so that the erroneous printing command and the cause of the error can be obtained without the printer device manufacturer having to visit the server to check the job data. This improves the efficiency and accuracy of analyzing the cause of the error, thereby improving the efficiency and accuracy of driver updates and avoiding the leakage of user confidential information.
