Roll paper box of roll paper printer and control method

Abstract

The invention relates to a roll paper box of a roll paper printer, a control method and a computer readable storage medium. The roll paper box comprises a supply roll paper shaft, a storage roll paper shaft and a control module, wherein the supply roll paper shaft is used for bearing paper rolls to be printed and is capable of moving in a distance range of a maximum paper roll radius from one side wall of the roll paper box; the storage roll paper shaft is used for bearing printed paper rolls and is capable of moving in a distance range of a maximum paper roll radius from one opposite side wall of the roll paper box; and the control module is configured to obtain the roll paper thickness of the supply roll paper shaft and the roll paper thickness of the storage roll paper shaft in real time, control the supply roll paper shaft to move in a direction close to the side wall according to the variation of the roll paper thickness of the supply roll paper shaft, and control the storage roll paper shaft to move in a direction away from the opposite side wall according to the variation of the roll paper thickness of the storage roll paper shaft. According to the roll paper box of the roll paper printer, the positions of all the roll paper shafts in the roll paper box can be adjusted, so that the space utilization rate of a paper box device is increased, and the miniaturization improvement of the roll paper box is achieved.

Description

technical field [0001] The present invention relates to the control technology of roll paper printers, in particular to a miniaturized roll paper box with adjustable position of the roll paper shaft, a control method for controlling the movement of the roll paper shaft to meet the miniaturization requirements of the roll paper box, and a A computer-readable storage medium storing the control method. Background technique [0002] A roll paper printer is a relatively popular printer on the market, including a supply reel and a storage reel, which are respectively used to carry the paper roll to be printed and the printed paper roll. At present, the supply reel and storage reel of some roll paper printers are respectively installed in different paper box devices, while the supply reel and storage reel of another part of roll paper printers are installed in the same paper box. [0003] However, no matter which of the above-mentioned roll paper printers, the supply roll shaft an...
