AI Technical Summary

Problems solved by technology

[0006] The print command parameters sent by some applications to the printer driver via GDI are already incorrect, resulting in incorrect printing proportions or disordered positions
[0007] But not all applications support printing with asymmetric graphics resolution. Therefore, when users use some applications, they often find that some fonts or graphics are normal on the screen, but the printer prints them out. When an error occurs, it is the wrong output phenomenon of asymmetric graphic resolution.

Embodiment Construction

[0019] Firstly, please refer to FIG. 1A and FIG. 1B , which are schematic diagrams of transformation of asymmetrical graphics according to the embodiment of the present invention. And Fig. 2 is the flowchart of the present invention. The present invention is mainly used in the printer driver to output the print processing of the asymmetric graphic resolution, the resolution of the asymmetric graphic may be the symmetrical graphic resolution (x, y), and the horizontal (x) Z times the resolution in the direction, or Z times the resolution in the vertical (y) direction, i.e. (Zx, y) dpi or (x, Zy) dpi, the present invention takes 1200 × 600dpi asymmetric graphic resolution as an example to illustrate this The process of inventing the printer driver method.

[0020] This 1200 * 600dpi asymmetric graphic resolution, as Fig. 1B, is 600 * 600dpi symmetrical graphic, as Fig. 1A, 2 times of resolution in the horizontal (x) direction, so the present invention at first uses 600 * 600dpi...

Abstract

A printer driving method supporting asymmetric pattern resolution includes using symmetric structure to call GDI command for describing symmetric pattern resolution and interpreting its conversion command, generating a RGB 24 bit data and then carrying out colour converting to convert said data to be a CMYK 32 bit data, processing converted data by half - tone to convert each colour system of C, M, Y and K separately to multiple one bit scan line, then making each scan line long or short to generate printing output of asymmetric pattern resolution.

Description

technical field [0001] The invention relates to a printer driving method supporting asymmetric graphic resolution, in particular to a printer driver program capable of supporting printing of asymmetric graphic resolution. Background technique [0002] Due to the advancement of computer technology, personal computers have become indispensable supplies for modern people. In addition, printers are mostly accompanied by personal computers and are one of the most important peripheral products of personal computers. There are many types of printers, such as matrix printers, spray printers, etc. ink printer or laser printer. [0003] General printer drivers (Printer Driver) only support symmetrical graphic resolution (Resolution), such as 300×300dpi or 600×600dpi, etc., but now there are more and more high-end printers whose drivers can support Asymmetric graphic resolutions, such as 1200×600dpi or 2400×1200dpi, are especially common in ink-jet printers. [0004] In terms of know...
