Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of printing, and in particular to an image scaling printing control method and apparatus and a printing system. BACKGROUND OF THE INVENTION A conventional image scaling printing control method prints and outputs image data of a source image by using an interpolation algorithm according to a scaling ratio. For example, commonly used image scaling interpolation algorithms include nearest neighbor interpolation algorithm, bilinear interpolation algorithm and cubic convolution algorithm. The principle of the nearest neighbor interpolation algorithm is that a floating point coordinate obtained by inverse transformation is simply rounded to obtain an integer coordinate, and the pixel value corresponding to the integer coordinate is the pixel value of the target pixel. That is, the pixel value closest to the floating point coordinate in the source image is assigned to the target pixel value. The algorithm is characterized by fast data processing, but the enlarged image has a very serious mosaic, and the reduced image has severe distortion. . The pixel value of the floating point coordinates obtained by the inverse linear transformation algorithm is determined by the four real existing pixel values around the floating point in the source image. The algorithm is characterized by slow data processing and smooth image. However, bilinear interpolation has the property of a low-pass filter, which impairs high-frequency components, and thus blurs the outline of the image. The pixel value of the floating point coordinates obtained by the inverse convolution algorithm is determined by the pixel values of 16 neighbors around the floating point coordinates. This algorithm can overcome the shortcomings of the above two algorithms because of the high calculation accuracy, but The amount of calculation is large and the data processing speed is slower. The inventors have found that the scaling of printing by interpolation algorithm, the higher the image printing quality requirement, the higher the calculation accuracy requirement for the interpolation algorithm. However, the higher the calculation accuracy of the interpolation algorithm, the larger the amount of data processing calculation, resulting in slow data processing speed, which affects the printing speed.

With the image printing apparatus of the second embodiment, it is possible to correspond to a printing system composed of a printing requesting apparatus and a printer, by which the printing speed can be achieved while ensuring print quality. The image scaling print control apparatus of the embodiment of the present invention can be realized by the following printing system. 3 is a schematic diagram of a printing system in accordance with an embodiment of the present invention. As shown, the printing system includes a host 1 and a printer 2. The host 1 serves as a print requesting device corresponding to the image scaling print control device described above, and may be a computer or other control device, including a control unit 11, a storage unit 12, and a communication interface 13. Among them, the control unit 11 operates based on the operating system and the installer in the storage unit 12, thereby performing various information processing operations. The storage unit 12 includes a ROM memory, a RAM memory, and a hard disk drive. The storage unit 12 stores a program to be executed by the control unit 11. The storage unit 12 is also used to store various types of data required during the processing performed by the control unit 11. The installer in the storage unit 12 includes an application 14, a Graphics Device Interface (GDI) 15 and a printer driver 16. The application 14 includes a data generating unit 14a, a function invoking unit 14b, and a user interface 14c, wherein the data generating unit 14a is configured to create a device context (Device Context, abbreviated as DC), and generate source data into the device environment; The calling unit 14b is used to call the GDI function in the GDI 15 to make a graphic output request; the user interface 14c is used for the operator to perform data interaction with the application 14, for example, setting format information of the source data, printing configuration parameters, and the like. The GDI 15 is used for information exchange between the application 14 and the printer driver 16, and processes the graphical output request of the application 14. The GDI 15 rasterizes the source data generated by the application 14 through its internally set GDI function to generate bitmap data. The printer driver 16 includes a general printer description (abbreviated as GPD, abbreviated as Generic Printer Description) 16a and a user interface (hereinafter referred to as UI, abbreviated as User Interface) 16b, wherein the GPD 16a includes data structures and functions for describing the printer. Data on functions and capabilities, such as device resolution, color capabilities, and paper size supported by the printer, where device resolution refers to the printer's output resolution, ie, the printer can print up to two inches per inch in both horizontal and vertical directions. The number of dots printed, such as 600 dots per inch (ie 600 DPI, where DPI is the abbreviation for dot/inch), is stored in the data structure. The user interface 16b includes data structures and functions for the operator to interact with the printer driver 16 for data interaction. The operator can configure the printer's print parameters in the user interface 16b, such as the operator setting the number of prints, paper in the user interface. Size, scaling parameters, etc. GPD16a and UI16b interact with GDI15 via functions. The communication interface 13 is used to establish communication between the host 1 and the printer 2, and transmits data and instructions generated by the host 1 to the printer 2. When the function calling unit 14b of the application 14 calls the GDI function to make an image output request, the GDI 15 calls a corresponding function in the printer driver 16, such as a control function, a drawing function, etc., to interact with the printer driver 16, and the application 14 The created source data is rasterized to generate bitmap data. At the same time, GDI15 transfers the system's drawing instructions to the printer driver and calls the functions of printer driver 16. The function of printer driver 16 converts the drawing instructions into print instructions that the printer can execute, and printer driver 16 transmits the bitmap data and print instructions to the printer via communication interface 14. The first acquisition module 10 in the image scaling print control device can create a print job through the application 14 to acquire a print job. The second obtaining module 20 can be implemented by the user interface 14c of the application 14 or the UI 16b in the print driver 16, for example, if the zoom parameter input by the operator through the user interface 14c of the application 14 or the UI 16b in the print driver 16 is For the percentage value, the second acquisition module 20 directly uses the percentage value as the scaling ratio. The generation module 30 can also be implemented by the printer driver 16, which multiplies the acquired scaling ratio by the device resolution y saved in the printer driver to obtain a data processing resolution. The conversion module 40 can be implemented by the GDI 15 and the printer driver 16, and the GDI 15 and the printer driver 16 perform data interaction through function calls, converting the source data into pixel numbers and data processing resolution. The same bitmap data, the sending module 50 can be realized by the printer driver and the communication interface, and the printer driver sends the bitmap data and the printing command to the communication interface of the printer through the communication interface. The printer 2 includes a controller 21, a print buffer 22, a receiving buffer 23, a communication interface 24, and a print head 25. The controller 21 is used to control each module of the printer 2 to perform work. The communication interface 24 is connected to the communication interface 14 of the host through a wired cable or a wireless communication module, and is configured to receive print data delivered by the host or feed back the status of the printer 2 to the host 1. The receiving buffer 23 is configured to temporarily store the first print data received by the communication interface 24, the first print data including the bitmap data sent by the printer driver and the print instruction print buffer 22 for temporarily storing the second print data. The second print data is data generated by the controller 21 after processing the bitmap data according to the print instruction. It should be noted that the print buffer 22 and the receive buffer 23 may be separate RAM (random access memory) memories, or may be different storage areas in one RAM memory. The print head 25 is for printing bitmap data on the surface of the recording medium to form a visible image or text. The image scaling printing control method of the embodiment of the present invention is described below. It should be noted that the image scaling printing control method may be implemented by, but not limited to, the image scaling printing control device or the printing system provided by the above embodiments. 4 is a flow chart of an image zoom printing control method according to a first embodiment of the present invention. As shown in FIG. 4, the image zoom printing control method includes the following steps: Step S102: Acquire a print job; the obtaining a print job in the step may be receiving a print task from an external, or may be generated or created according to a user input. Print the task. Step S104, obtaining a zoom ratio according to the print job. Step S106, generating a data processing resolution according to the device resolution and the scaling ratio. Step S108, converting the source data in the print job into bitmap data according to the data processing resolution. Step S110, the device resolution and the bitmap data are sent to the printer. The above-described steps S102 to S110 may each be performed by the print requesting means, and after the bitmap request data is obtained, the print requesting means transmits the bitmap data to the printer for the printer to execute step S112. Therefore, the image scaling print control method described above may further include the following steps: Step S112, printing bitmap data according to device resolution, as shown in FIG. 5. FIG. 6 is a flowchart of a method for controlling image scaling printing according to a third embodiment of the present invention. The second embodiment can be used as a specific implementation of the image scaling printing control method of the first embodiment. The method includes the following steps: S201, creating a print job, proposing an image output requesting operator to create a print job through the application 14 and the printer driver 16, wherein the text file or the picture file is created by the application 14 and passed through the user interface and/or the printer of the application 14. The UI 16b of the driver 16 inputs the print configuration parameters. Print configuration parameters include print quantity, paper size, zoom parameters, and more. The zoom parameter may be set in the user interface 14c of the application 14 or in the UI 16b of the printer driver 16. The function calling unit 14b of the application 14 calls the GDI function of the GDI 15 to make an image output request. Step S202, the UI 16b of the zoom ratio printer driver 16 is acquired to obtain a zoom ratio. If the zoom parameter input by the operator through the UI 16b is a percentage value, such as 60%, the UI 16b of the printer driver 16 may directly obtain the zoom ratio x%; The zoom parameter input by the operator through the UI 16b is the destination page size. If the destination page size is A5, the printer driver 16 also needs to calculate the zoom ratio x% from the values of the original page size and the destination page size. Step S203, generating a data processing resolution according to the scaling ratio and the device resolution. The printer driver 16 multiplies the obtained scaling ratio x% by the device resolution y saved in the data structure of the printer driver 16, to obtain a data processing resolution. , ie z=y*x%. The printer driver 16 saves the data processing resolution z to the data structure, ie the device resolution in the data structure of the printer driver is reassigned to the data processing resolution z, but the assignment is only valid for this print job. When the next print job is initiated, the device resolution parameter of the printer driver's data structure is reinitialized to the device resolution. Step S204, converting the source data into the bitmap data GDI15 according to the data processing resolution and the printer driver 16 perform data interaction through the function call, and convert the source data into bitmap data having the same number of pixels and the same data processing resolution. Figure 7 is a schematic diagram of the interaction process between the GDI and the printer driver. As shown in the figure, during the interaction between GDI and the printer driver, GDI calls the relevant function of the print driver, such as GDI by calling The DrvEnableDriver function initializes the printer driver and returns a list of DLLs supported by the printer driver. GDI returns the description of the physical device properties to GDI by calling the DrvEnablePDEV function. GDI notifies the printer driver physical device by calling the DrvCompletePDEV function. The installation has been completed. This function also provides the driver with a logical handle to the GDI of the PDEV (abbreviation of the physical device) for the driver to use in calling the GDI function. GDI calls DrvEnableSurface to cause the printer driver to create the surface to be drawn and Associate it with PDEV. At the same time, the print driver calls back the GDI output function in the process of implementing the above functions. For example, the printer driver requests the GDI to create and manage the bitmap by calling the EngCreateBitmap function, and sets the surface as the binding surface by calling the EngMarkBandingSurface function. For surface creation, the printer driver must associate the surface with a PDEV by calling GDI's EngAssociateSurface function, which also tells the GDI printer driver which drawing function to hang on the surface. Thus, the GDI 15 and the printer driver 16 perform data interaction by function calls, and convert the source data into bitmap data having the same number of pixels as the data processing resolution. For example, set the device resolution to 300 DPI. When the zoom ratio is 50%, the data processing resolution is 150 DPI. GDI15 converts the source data into bitmap data with the same number of pixels and the data processing resolution of 150 DPI, that is, the source data is converted into each. Bitmap data with 150 pixels in pixels; when the zoom ratio is 100% (ie, no scaling), the data processing resolution is 300 DPI, which is equal to the device resolution, and GDI15 converts the source data into pixel numbers and data processing resolution of 300 DPI. The same bitmap data, the source data is converted into bitmap data with 300 pixels per inch; when the zoom ratio is 200%, the data processing resolution is 600DPI, GDI converts the source data into pixel number and data processing resolution The 600DPI has the same bitmap data, which converts the source data into bitmap data with 600 pixels per inch. Step S205, the printer driver sends the bitmap data and the print command to the printer printer driver to send the bitmap data and the print command to the communication interface of the printer through the communication interface. The controller of the printer saves the received bitmap data and print instructions to the receive buffer. At the same time, the controller processes the bitmap data according to the print command, for example, adding a start character, a terminator, and The capacity description, etc., and save the processed per-pixel row data to the set address in the print buffer. Step S206, the printer prints the bitmap data according to the device resolution. The controller of the printer sends the bitmap data in the print buffer to the print head line by line, and the print head outputs the bitmap data according to the device resolution in the horizontal and vertical directions. When the device resolution is 300DPI, the number of pixels per inch is 300DPI, when the zoom ratio is 50%, the data processing resolution = 300DPIx50% = 150DPI, so that the number of pixels per inch is 150 points in the horizontal and vertical directions. . Therefore, when printing bitmap data with a width of one inch and a length of one inch, in the print width direction, The number of pixels generated by the device resolution is 300x1=300 points, the number of pixels generated by the data processing resolution is 150x1=150 points, and the number of pixels generated by the device resolution in the print length direction is 300x1=300 points. The number of pixels generated by the data processing resolution is 150x1=150 points, so that when the same printer prints one-inch wide and one-inch wide bitmap data, the number of pixels of the bitmap data generated by the data processing resolution is larger. The number of pixels of the bitmap data generated by the device resolution is reduced by 0.5 times in both the horizontal and vertical directions, so the print width becomes 0.5 times, the print length is also 0.5 times, and the print area is 0.25 times. , thus achieving the purpose of reducing printing. When the zoom ratio is 200%, the data processing resolution = 300 DPIx 200% = 600 DPI, so that the number of pixels per inch becomes 600 points. Therefore, when printing bitmap data with a width of one inch and one inch of length, in the print width direction, the number of pixels generated by the device resolution is 300x1=300 points, and the number of pixels generated by the data processing resolution is 600x1. =600 points, in the print length direction, the number of pixels generated by the device resolution is 300x1=300 points, and the number of pixels generated by the data processing resolution is 600x1=600 points, so that the same printer prints one inch wide, When the bitmap data is one inch wide, the number of pixels of the bitmap data generated by the data processing resolution is increased by 2 times in the horizontal and vertical directions than the number of pixels of the bitmap data generated by the device resolution, so the print width is It is twice as large as the original, the print length is also doubled, and the print area is 4 times that of the original, thus achieving enlargement printing. According to the image scaling print control method of the embodiment of the present invention, the data processing resolution is generated by the printer driver according to the zoom ratio and the device resolution, and the GDI and the printer driver perform data interaction through function calls, converting the source data into pixel numbers and data processing. With the same bitmap data, the printer prints the bitmap data according to the device resolution, so that the source data is scaled proportionally in the print width direction and the print length direction. Compared with the prior art, the embodiment of the present invention uses the GDI and the printer driver to rasterize the source data, and only needs to increase or decrease the number of pixel points in the bitmap data according to the scaling ratio, and does not need to calculate the pixel value according to the interpolation algorithm. Therefore, the data processing speed is fast and the print quality is high. The present application also provides a computer read-only storage medium storing a computer program for executing the image scaling print control method of the first embodiment. The computer read-only storage medium may be a conventional optical disc, a USB flash drive or the like, or may be a storage medium provided by the Internet for storing a downloadable computer program. The image scaling printing control scheme provided by the embodiment of the present invention can be implemented by the operator installing the computer program in a print requesting device, such as a host, and then connecting the print requesting device and the printer. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
