s101, a virtual printer acquires printing data and sends the printing data to a raster image processor;
in this embodiment, the print data includes: the data head records precision size information of the image, and the data content records data information of each pixel point of the image. The invention separates the data head and the data content, and the subsequent virtual printer and the raster image processor can directly acquire the data head or the data content according to the processing requirement, thereby being convenient for data processing.
Illustratively, the print data is image data in CAD format, and the virtual printer obtaining the print data and sending the print data to the raster image processor includes:
s1, the virtual printer acquires the CAD image data according to the CAD calling instruction, and performs zooming processing with preset precision on the CAD image data;
s2, sending the scaled CAD image data to the raster image processor in the form of image matrix data.
Specifically, the method comprises the following steps:
s1011, the virtual printer acquires printing data and performs scaling processing with preset precision on the printing data;
in this embodiment, the driver of the virtual printer is developed by researching a printer interface provided by the microsoft system, and when a file to be printed, such as a CAD file, a JPG file, a Word document, a TXT text, or the like, calls a virtual printer nozzle to print, the driver of the virtual printer may acquire image data of the CAD file and support zooming of preset precision on the image data. Wherein the preset precision can be set according to precision size information of the image recorded in the data head.
In this embodiment, when a file to be printed calls the virtual printer nozzle to print, the virtual printer acquires print data of the file to be printed, and meanwhile, the virtual printer generates a print task to be sent to the raster image processor. As shown in fig. 2, the print job includes print information such as document name, status, owner, number of pages, size, delivery time, and port.

In addition, the user operation instruction may also be input directly by the user to the printer model, color combination, printing scheme, algorithm type for setting use of rasterized data, and file output manner. For example, the user makes direct input through a keyboard, or the user makes direct input through a stylus.

For two different forms of file output manners in step S1022, the printing manners in this step are also different, specifically:
if the raster image processor directly outputs the processed printing data to the printing control module, the printing control module directly acquires the processed printing data and controls a printer nozzle to print according to the processed printing data;
and if the raster image processor stores the processed printing data into a printing drive file, the printing drive file is sent to the printing control module, the printing control module loads the printing drive file to acquire the processed printing data, and the printer nozzle is controlled to print according to the processed printing data.
The printing control method provided by the invention comprises a data head and data content in the printing content, wherein the data head records the precision size information of the image, and the data content records the data information of each pixel point of the image. The virtual printer can directly obtain the content of the file to be printed; the raster image processor can ensure the color and the precision of the output file through color correction and screening processing, and finally used printers are not limited to desktop office printers, but also can be large-format photo machines, inkjet printers, flat-plate machines and the like, so that the requirement of large-format output is met.
Based on the above-mentioned various method embodiments, the present invention also provides the following apparatus embodiments.
Example two
An embodiment of the present invention provides a print control method, as shown in fig. 4, the method includes:
s201, the virtual printer acquires a plurality of printing data and printing identification information.
Wherein the print data comprises a print job.
In a particular embodiment, printing the identification information includes: a print priority.
S202, calculating the printing time length of each piece of printing data according to the preset printing speed.
The printing speed of the printer can be the printing time required by each page, and the printing speed can be stored in the device in advance by related personnel, and the printing time is the product of the number of pages to be printed and the printing time required by each page.
S203, sequentially sending each printing data to a raster image processor according to the printing identification information and the printing duration;
specifically, the method comprises the following steps:
s2031, the virtual printer acquires each piece of printing data, and performs scaling processing with preset precision on each piece of printing data;
in this embodiment, a driver of the virtual printer is developed by researching a printer interface provided by the microsoft system, and when a file to be printed, such as a CAD file, calls a virtual printer nozzle to print, the driver of the virtual printer may acquire image data of the CAD file and support scaling of preset precision on the image data. Wherein the preset precision can be set according to precision size information of the image recorded in the data head.
In this embodiment, when a file to be printed calls the virtual printer nozzle to print, the virtual printer acquires print data of the file to be printed, and meanwhile, the virtual printer generates a print task to be sent to the raster image processor. The print job includes, among other things, the document name, status, owner, number of pages, size, rendering time, and port, among other print information.
S2032, sending the printing data to a raster image processor in the form of image matrix data.
Specifically, after the virtual printer acquires each piece of data to be printed, the virtual printer determines a printing sequence according to the printing priority in the printing identification information, and determines a time interval for sending each piece of printing data to the raster image processor according to the printing duration.
For example, the print priorities of the print data a, the print data b, and the print data c are: print data b > print data a > print data c, the print time of print data a, print data b, print data c respectively being: the first print time T1, the second print time T2, and the third print time T3, the virtual printer sends print data b to the raster image processor first, sends print data a to the raster image processor after the second print time T2, and sends print data c to the raster image processor after the first print time T1.
S204, the raster image processor sequentially receives the printing data sent by the virtual printer, performs color correction and gridding processing on the printing data, and sends the processed printing data to the printing control module;
in this step, the raster image processor receives the print data sent by the primary virtual printer, immediately performs color correction and gridding processing on the received print data, and sends the processed print data to the print control module.
For example, when receiving the print data b, the raster image processor 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 printing time T2, the raster image processor receives the print data a, 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 printing time T1, the raster image processor receives the print data c, performs color correction and gridding processing on the print data c, and sends the processed print data to the print control module.
In this step, the specific implementation process of the raster image processor performing color correction and gridding processing on the print data and sending the processed print data to the print control module is the same as that in step S102, and is not described herein again.
The color correction and the gridding process may be performed first, and then the gridding process is performed.
And S205, the printing control module controls the printer nozzle to print according to the processed printing data.
