Mobile printing device and auxiliary positioning device thereof

Abstract

The invention discloses a mobile printing device and an auxiliary positioning device thereof. The mobile printing device is provided with a first positioning structure block at one side or two sides along the mobile printing direction, and the first positioning structure block is used for cooperating with the auxiliary positioning device so as to position the line printing starting point of the mobile printing device. The auxiliary positioning device is provided with a straight edge, a plurality of second positioning structure blocks consistent in size and interval are arranged on the straightedge, the second positioning structure blocks are used for being matched with the first positioning structure block arranged on the mobile printing device in a clamped mode so as to guide the mobileprinting device to be positioned, and the center distance between every two adjacent second positioning structure blocks is the line printing height of the mobile printing device. According to the mobile printing device, through cooperation of the auxiliary positioning device, the content of the to-be-printed pattern does not need to be specially limited or arranged, the printing splicing operation of the mobile printing device can be simplified and optimized, and the printing splicing effect is improved.

Description

technical field [0001] The invention relates to the field of portable mobile printing, in particular to a mobile printing device and an auxiliary positioning device thereof. Background technique [0002] The desktop flat printer controls the line-by-line printing of the print head through a two-dimensional mobile device, so as to realize flat printing. [0003] The portable mobile printer is small in size, and there is no two-dimensional mobile device for moving the print head inside. The printing method is to manually move the portable mobile printer, and record its movement trajectory through the internal photoelectric sensor and other displacement sensors, and send the The movement trajectory corresponds to the pixel block of the pattern to be printed, so as to implement printing. [0004] Portable mobile printers have natural defects in printing splicing because their movement trajectory during printing is manually controlled, and the starting point of printing cannot b...

AI Technical Summary

Problems solved by technology

[0004] Portable mobile printers have natural defects in printing splicing due to the fact that their movement trajectory during printing is manually controlled, and the starting point of printing cannot be effectively defined.

Therefore, when printing splicing, there are problems such as misalignment, overlap and skew between lines, which affect the splicing quality

This defect is usually achieved by typesetting the pattern to be printed in the smart terminal APP according to the row printing height of the mobile printer, and dividing it into multiple independent patterns that do not cross rows, so as to minimize the impact of misalignment, overlap and inclination between rows

However, in most cases, it is difficult for the content to be printed to meet the typesetting requirements, and each typesetting requires a lot of time and energy, which brings a lot of inconvenience to the user
