Abstract
A double-paper-roll printing device includes an installation frame for installing the following components and paper rolls. A first paper roll and a second paper roll are installed on the installation frame through a paper roll supporting shaft. Paper tapes of the first paper roll and the second paper roll are selectively fed to a printing component through paper passages. The first paper roll and the second paper roll are selectively fed to the printing component through a first paper passage and a second paper passage that are mutually independent. The first paper passage and the second paper passage are mutually superposed. The tail end of the first paper passage and the tail end of the second paper passage form an intersecting end, and paper tape heads of the paper rolls enter the printing component through the intersecting end.
