printer

Abstract

The invention discloses a printer. The printer comprises a shell, and a fixed frame fixed in the shell, wherein a printing head and a paper feeding channel are arranged in the fixed frame; the paper feeding channel comprises a printing area, and two or more to-be-printed areas communicated with the printing area; the printing area is output to a paper outlet of the fixed frame, and is opposite to the printing head; and each of the to-be-printed areas is input to a paper inlet of the fixed frame. Multiple to-be-printed areas communicated with the printing area are arranged in the fixed frame of the printer; the printing area is used for printing rolled papers through the printing head; the to-be-printed areas are used for conveying the rolled papers; each of the to-be-printed areas can convey the rolled papers to the printing area, and can independently work; and the working of the rest to-be-printed areas cannot be influenced by incapacity of working of any one to-be-printed area due to such faults as paper blockage and paper jam, so that the printer can guarantee good printing speed, can guarantee good printing quality, and can bring good printing experience to users.

Description

technical field [0001] The invention relates to the technical field of roll paper printing, in particular to a printer. Background technique [0002] Printers are widely used, many jobs are inseparable from printers, and the dependence on printers is getting stronger and stronger. Existing printers only have a single paper roll placement position and a single medium paper path. Limited by the amount of paper that a single paper roll can hold, the printer needs to change the roll frequently. Every time the roll is changed, the printer needs to be opened to take out the used roll paper. Loading a new paper roll, frequent replacement and multi-step operation will bring great inconvenience to the work, and it is easy to cause operation errors to cause unstable printing effect, which greatly affects the printing work efficiency, and because it is a single-medium paper-feeding channel , if the paper path fails, the printing operation will not be possible.
