Abstract

The present invention provides a printing medium height adjustment and control method for adjusting and controlling the height of the printing medium in a printing device. It is characterized in that it includes: step a, before starting printing, controlling the level of a carrying unit carrying the printing medium. Run, and while running, detect the vertical distance between the print media surface and the print head end face; step b, during the above running detection process, once the vertical distance between somewhere on the print media surface and the print head end face is detected is less than the predetermined distance, then control the carrying unit to stop running horizontally and run downward until the vertical distance between the surface of the printing medium and the end face of the print head is not less than the predetermined distance; and step c, repeat the above steps a and b until The vertical distance between the entire surface of the printing medium and the end face of the print head is detected to be no less than a predetermined distance. The invention also provides a printing device.

Description

technical field [0001] The invention relates to a printing medium height adjustment control method and a printing device. Background technique [0002] Generally, an appropriate printing distance should be maintained between the end face of the print head of the inkjet printer and the printing medium. If the distance is too far, the printing effect will be unsatisfactory, and if the distance is too close, it will cause mechanical failure or mechanical damage due to the print head touching the printing unit. [0003] Unlike ordinary printing paper, some types of printing media vary in thickness and may have uneven surfaces. For example, T-shirts (hereinafter also referred to as "T-Shirts") are often of variable thickness and may have an uneven surface due to having necklines, pockets, trims, and the like. During printing on a printing medium such as T-Shirt, the distance between the surface of the printing medium and the end surface of the print head is uncertain. [0004]...
