[0002] With the widespread use of computers in graphics or word processing, the use of printers has become more and more common. Through printers, people can easily output text or graphics in computers to pictures.

[0003] In the current printing system, the printer issues a print command through a computer, and the printer prints the information sent by the computer. Common printers include inkjet printers and laser printers. Inkjet printers use a nozzle to print, while laser printers use a laser beam and a photosensitive drum for electrostatic printing. Inkjet printers are widely used in the field of industrial printing because of their low price.

[0004] In common printing scenarios, such as the printing of CAD images, the CAD software is usually directly connected to the desktop office printer nozzle for printing output without any processing of the print data.

[0051] The specific embodiments of the present invention are described in detail below.

[0052] Embodiment 1

[0053] like Figure 1 The printing control method provided in the first embodiment of the present invention is shown, and the method includes:

[0054] S101, the virtual printer acquires print data and sends the print data to a raster image processor;

[0055] In this embodiment, the print data includes: a data header and data content, the data header records the precision size information of the image, and the data content records the data information of each pixel of the image. The present invention separates the data header and the data content, and the subsequent virtual printer and raster image processor can directly obtain the data header or the data content according to processing needs, which is convenient for data processing.

[0056] Exemplarily, the print data is image data in a CAD format, and the virtual printer acquires the print data and sends the print data to the raster image processor, including:

[0057] S1. The virtual printer obtains the CAD image data according to the CAD calling instruction, and performs scaling processing on the CAD image data with a preset precision;

[0058] S2. Send the scaled CAD image data to a raster image processor in the form of image matrix data.

[0059] Specifically, this step includes:

[0060] S1011, the virtual printer obtains print data, and performs scaling processing on the print data with a preset accuracy;

[0061] In this embodiment, the driver of the virtual printer is developed by studying the printer interface provided by the Microsoft system. When the file to be printed, such as a CAD file, a JPG file, a Word document, a TXT text, etc., is called to print by the virtual printer nozzle, the driver of the virtual printer can obtain the image data of the CAD file and support scaling the image data with a preset precision. The preset precision can be set according to the precision size information of the image recorded in the data header.

[0062] In this embodiment, when the file to be printed calls the virtual printer nozzle for printing, the virtual printer will obtain the print data of the file to be printed, and at the same time, the virtual printer generates a print task to be sent to the raster image processor. Figure 2 As shown, the print task contains printing information such as document name, status, owner, number of pages, size, submission time and port.

[0063] S1012: Send the print data to a raster image processor in the form of image matrix data.

[0064] Specifically, after acquiring the data to be printed, the virtual printer sends the data to be printed to the raster image processor in the form of image matrix data.

[0065] S102, the raster image processor performs color correction and gridding processing on the print data, and sends the processed print data to the print control module;

[0066] Specifically, this step includes:

[0067] S1021, the raster image processor obtains the printer model, color combination, printing scheme, and sets the algorithm type used for rasterizing the data and the file output mode of the printing data;

[0068] Specifically, the raster image processor may obtain the printer model, color combination, printing scheme, and the type of algorithm used to set the rasterized data and the file output mode according to the user operation instruction;

[0069] The user operation instruction may be the user's choice of printer model, color combination, printing scheme, algorithm type used for setting rasterized data, and file output method. Figure 3 The print setting selection box shown in the figure displays the options of printer model, curve selection, screening mode, working mode, color combination, port selection, raster image processor thread priority, sending thread priority, pre-printing buffer time, file output directory and temporary file directory in the form of a drop-down list box for users to choose. Among them, curve selection represents setting the printing scheme, screening mode represents setting the algorithm type used for rasterization data, and port selection represents setting the file output mode. The user can complete the input of user operation instructions by selecting each drop-down list box. In addition, the user can also set the display to a touch display screen, set corresponding virtual touch buttons for the printer model, color combination, printing scheme, setting the algorithm type used for rasterization data and file output mode, and the user can complete the selection of the parameters corresponding to the virtual touch button by touching the virtual touch button in a predetermined manner. The present invention is designed by the above scheme to print out an image with no restrictions on size, which meets the needs of large-size image output; the printing precision of CAD files is high, and even when the original file size is large and the output size is small, the output will not cause the details of the image to be blurred; it can be a multi-nozzle, and the printing speed is fast.

[0070] In addition, the user operation instruction may also be the user's direct input of the printer model, color combination, printing scheme, the type of algorithm used to set the rasterized data, and the file output method, for example, the user directly inputs through a keyboard, or the user directly inputs through a stylus pen.

[0071] S1022, performing color correction and gridding processing on the print data according to the printer model, color combination, print scheme, algorithm type used for setting rasterized data, and file output mode;

[0072] A raster image processor is an interpreter that converts the layout information (various images, graphics and text) described in a page description language into data information that can be output by an output device, and outputs it to a specified output device. It can also be said that it interprets images, graphics and text into a language that a printer can recognize.

[0073] In this embodiment, the raster image processor is a tool that can convert PostScript information generated by image processing and typesetting software into a high-resolution dot matrix image. The generated image can be output on paper or film by a laser printer, inkjet printer or phototypesetter.

[0074] In this embodiment, the file output mode includes two modes:

[0075] Method 1: Output directly to the print control module;

[0076] Method 2: Generate a print driver file and save it locally, then send it to the print control module.

[0077] The print driver file may be a PRN file; the algorithm type used for rasterized data may be an anti-aliasing algorithm or the like.

[0078] S1023: Output the processed printing data to the printing control module.

[0079] S103: The printing control module controls the printer nozzle to print according to the processed printing data.

[0080] Specifically, this step includes:

[0081] The printing control module loads, obtains and processes the printing data, and controls the printer to print out according to the data header and data content of the printing data.

[0082] Among them, for the two different forms of file output methods in step S1022, the printing methods of this step are also different, specifically:

[0083] If the raster image processor directly outputs the processed print data to the print control module, the print control module directly obtains the processed print data and controls the printer nozzle to print according to the processed print data;

[0084] If the raster image processor saves the processed print data as a print driver file and then sends it to the print control module, the print control module loads the print driver file to obtain the processed print data, and controls the printer nozzle to print according to the processed print data.

[0085] The printing control method provided by the present invention includes a data header and data content in the printing content, wherein the data header records the precision size information of the image, and the data content records the data information of each pixel of the image. The virtual printer can directly obtain the content of the above-mentioned file to be printed; the raster image processor can ensure the color and precision of the output file through color correction and screening processing, and the printer finally used is not limited to desktop office printers, but can also be large-format photo machines, inkjet printers and flatbed machines, etc., to meet the needs of large-format output.

[0086] Based on the above method embodiments, the present invention also provides the following device embodiments.

[0087] Embodiment 2

[0088] Embodiment 2 of the present invention provides a printing control method, such as Figure 4 As shown, the method includes:

[0089] S201: The virtual printer obtains a plurality of printing data and printing identification information.

[0090] Wherein, the printing data includes a printing task.

[0091] In a specific implementation, the printing identification information includes: printing priority.

[0092] S202: Calculate the printing time of each printing data according to a preset printing speed.

[0093] Among them, regarding the calculation of the printing time required by the printer, specifically, the printing task includes the number of printed pages, and the printing speed of the printer can be the printing time required for each page, which can be pre-stored in the device by relevant personnel. The printing time is the product of the number of printed pages and the printing time required for each page.

[0094] S203, sending each of the printing data to a raster image processor in sequence according to the printing identification information and the printing duration;

[0095] Specifically, this step includes:

[0096] S2031, the virtual printer obtains each print data, and performs scaling processing with a preset precision on each print data;

[0097] In this embodiment, the driver of the virtual printer is developed by studying the printer interface provided by the Microsoft system. When a file to be printed, such as a CAD file, calls the virtual printer nozzle for printing, the driver of the virtual printer can obtain the image data of the CAD file and support scaling the image data with a preset precision. The preset precision can be set according to the precision size information of the image recorded in the data header.

[0098] In this embodiment, when the file to be printed calls the virtual printer nozzle for printing, the virtual printer will obtain the print data of the file to be printed, and at the same time, the virtual printer generates a print task to be sent to the raster image processor. The print task contains printing information such as document name, status, owner, number of pages, size, submission time and port.

[0099] S2032: Send the print data to a raster image processor in the form of image matrix data.

[0100] Specifically, after acquiring each piece of data to be printed, the virtual printer determines the printing order according to the printing priority in the printing identification information, and determines the time interval for sending each piece of printing data to the raster image processor according to the printing duration.

[0101] For example, the printing priorities of print data a, print data b, and print data c are: print data b>print data a>print data c, and the printing times of print data a, print data b, and print data c are: first printing time T1, second printing time T2, and third printing time T3, respectively. The virtual printer first sends print data b to the raster image processor, and after the second printing time T2, sends print data a to the raster image processor, and after the first printing time T1, sends print data c to the raster image processor.

[0102] S204, the raster image processor sequentially receives the print data sent by the virtual printer, performs color correction and gridding processing on the print data, and sends the processed print data to the print control module;

[0103] In this step, the raster image processor receives the print data sent by the virtual printer once, immediately performs color correction and gridding processing on the received print data, and sends the processed print data to the print control module.

[0104] For example, when the raster image processor receives print data b, it performs color correction and gridding processing on the print data b, and sends the processed print data to the print control module. After the second print time T2, the raster image processor receives print data a, and performs color correction and gridding processing on the print data a, and sends the processed print data to the print control module. After the first print time T1, the raster image processor receives print data c, and performs color correction and gridding processing on the print data c, and sends the processed print data to the print control module.

[0105] In this step, the raster image processor performs color correction and gridding processing on the print data, and sends the processed print data to the print control module. The specific implementation process is the same as step S102, which will not be repeated here.

[0106] Among them, the color correction and gridding processing can be performed by first performing the color correction and then performing the gridding processing.

[0107] S205. The printing control module controls the printer nozzle to print according to the processed printing data.
