Problems solved by technology

No matter what kind of printers, although their printing principles are different, the paper feeding mechanism in the structure is an indispensable part. Due to the existence of the paper feeding mechanism, the volume of the printer cannot be made very small (the length of the A4 format printer must be It is greater than the width of A4 paper (21mm), and it also limits the maximum format that each printer can print (A4 format printers cannot print A3 paper), thus limiting the portability of office printers (A4 paper printers), thus from one side Restricts the application, popularization and development of portable office printers

Abstract

The invention relates to a handheld ink-jet printer. The handheld ink-jet printer is composed of a case 1, a printing cartridge 2, a laser scanning device 3, an origin positioning system 4 and driving software 5, and an ink-jet printing head 6 and a cartridge 7 are integrated, so as to form the printing cartridge 2. The printing cartridge 2, the laser scanning device 3 and the origin positioning system 4 are all arranged in the case 1, so as to form a handheld ink-jet printer 8, and the driving software 5 is arranged in a corresponding computer. Before printing, firstly the origin positioning system 4 is utilized to determine the datum point of the current printing operation; when printing, the handheld printer does continuous scanning movement on printing medium, so that ink jet printing is carried out, scanning accuracy is more than or equal to 2000dpi, and printing accuracy is more than or equal to 4800x1210dpi. The handheld ink-jet printer 8 can be provided with one black cartridge and one colour cartridge for colour printing or can be provided with two black cartridges for high load single colour printing. The printing cartridge 2 can be conveniently connected with a continuous ink supply system 9 for superhigh load continuous printing, and meanwhile the continuous ink supply system supplements ink to the cartridge.

Description

technical field [0001] The invention relates to a hand-held inkjet printer. In particular, it relates to a hand-held inkjet printer without a paper feeding system. The hand-held inkjet printer scans and moves on the recording medium (such as printing paper) in a hand-held manner to complete the printing job. Background technique [0002] Traditional printers are mainly divided into dot matrix printers, inkjet printers, laser printers, thermal transfer printers, etc. according to their working principles. No matter what kind of printers, although their printing principles are different, the paper feeding mechanism in the structure is an indispensable part. Due to the existence of the paper feeding mechanism, the volume of the printer cannot be made very small (the length of the A4 format printer must be It is greater than the width of A4 paper (21mm), and it also limits the maximum format that each printer can print (A4 format printers cannot print A3 paper), thus limiting ...
