Embodiment Construction

[0030] In the drawings, the thicknesses of layers or regions are exaggerated for clarity in illustrating examples.

[0031] refer to image 3 According to an embodiment of the present invention, the inkjet printer adopting the printing control method includes (along the conveying direction of the printing paper P): a pick-up roller 12 that picks up the paper P in the cassette 11 one by one, conveys the picked-up printing paper The conveying roller 13, the supply roller 14 and the idle roller 15 that accept the printing paper P from the conveying roller 13 and feed the accepted printing paper P linearly, and the output roller 16 and the star wheel 17 that output the printed printing paper.

[0032] The inkjet printer also includes a carriage 20, a carriage motor 22, a platen 50 on which printing paper is flatly placed, and a printing head 32 that ejects ink from the ink cartridge 30 onto the printing paper P on the platen 50. . Platen 50 and printhead 32 are mounted between s...

Abstract

A method of controlling printing in an inkjet printer having a paper feeding device, wherein the method includes the steps of: detecting a first printing paper on which first data will be printed and a second printing paper on which second printing data will be printed paper to determine whether printing paper is double-fed, wherein two sheets of printing paper are supplied by a paper feeding device, and when it is determined that the printing paper is double-fed, reprinting the first data on the second printing paper .

Description

technical field [0001] The present invention relates to a method and apparatus for controlling printing in an inkjet printer. More particularly, the present invention relates to a method and apparatus for controlling printing in an inkjet printer when a sheet of printing paper is conveyed while being overlapped with another sheet of printing paper. Background technique [0002] Inkjet printers generally include units that prevent double feeding of printing paper, such as friction pads that provide friction to another sheet of printing paper that is overlapping the paper to be printed on. However, even with the use of the paper double feed preventing unit, the paper may overlap another paper while being conveyed, so that the paper may be damaged. [0003] In a printer, a general paper supply method includes a box-type and a cassette-type mechanism for accommodating printing paper corresponding to a device. [0004] In the box feeding method, when double feeding of printing ...
