Abstract

The invention discloses a printing assembly, a printer and a printing system. The printing assembly comprises a first toner cartridge unit and a second toner cartridge unit, wherein a paper rail is arranged between the first toner cartridge unit and the second toner cartridge unit, the first toner cartridge unit is used for printing first content on the first surface of target paper in the paper rail, and the second toner cartridge unit is used for printing second content on the second surface of the target paper in the paper rail. The target paper does not need to be turned over or pass the paper rail twice, double-surface printing can be completed as long as the target paper passes through the paper rail once, and therefore the printing speed is increased, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a printing component, a printer and a printing system. Background technique [0002] With the development of society, there are more and more functional requirements for double-sided printing of printers in enterprises. [0003] In the existing double-sided printing, after printing one side first, the paper is sucked back from the paper outlet, turned over and then printed on the other side, which is slow and the printing efficiency is low. Contents of the invention [0004] In view of this, the present invention provides a printing component, a printer and a printing system to solve the technical problems of slow speed and low efficiency in double-sided printing in the prior art. [0005] The present invention provides a printing assembly, including: a first drum unit and a second drum unit, wherein: [0006] A paper track is set between the first drum unit and the...
