[0124] next use Figure 9 with Figure 10 , to describe the first embodiment of the present invention. Figure 9 It is a schematic diagram showing the positional relationship between the print head 36, the reflected light sensor 29, and the printing paper P. Figure 10 is a flowchart for explaining the first embodiment.

[0125] First, the user instructs printing through the application program 95 or the like (step S2). When the application program 95 receiving this order issued a print instruction, the printer driver 96 of the computer 90 received image data from the application program 95, and converted this data into print data PD, and the print data included the Raster data of the state of the light spot formed during scanning, and data indicating the feed amount of the sub-scan. Also, the printer driver 96 supplies the print data PD to the color inkjet printer 20 together with various commands COM. The color inkjet printer 20 sends the data to the image buffer 52 or ...

Abstract

It is possible to realize a printing apparatus, printing method, computer program, and computer system capable of reducing consumption of ink. The printing apparatus includes a printing head capable of moving in the main scan direction and printing medium feed means for feeding a printing medium. Ink is discharged from the printing head to print the printing medium. The leading edge of the printing medium fed by the printing medium feed means is detected at a plurality of points so as to calculate an inclination of the printing medium. According to the inclination calculated, the ink discharge start position or end position from the printing head moving in the main scan direction or both of them are changed.

Description

technical field [0001] The present invention relates to a printing device, a printing method, a computer program and a computer system. Background technique [0002] A color inkjet printer is well known as a typical printing device. A color ink-jet printer having an ink-jet print head for discharging ink from nozzles, a printer configured to record images, text, etc., by causing ink droplets to fall on printing paper; the printing paper is only an example of a printing medium . [0003] In addition, the print head is supported on a carriage, which is an example of a movable moving member, and the print head is set in such a state that the nozzle faces formed by the respective nozzles face the printing paper. , and the print head moves along a guide in the width direction of the printing paper (executes main scanning), and ejects ink in synchronization with the main scanning. [0004] In recent years, color inkjet printers capable of realizing so-called borderless printing...
