The following details the operation of the printer 100 with scanning function of the present embodiment:
in this embodiment, when a controller (not shown) of the printer 100 receives a print request, it controls the print medium in the paper storage to travel along the paper feeding path S1 through the relevant conveying roller of the core assembly 122, and when the print medium travels to a position below the print head assembly 121, the controller selectively drives the corresponding heating element on the print head assembly 121 according to the current print content, so as to realize the reproduction of the print content on the print medium. Generally, the printer 100 of the present embodiment is applied to printing an express receipt, and therefore, a print medium generally includes a printed barcode, a two-dimensional code, a character string, or other identification patterns.
In this embodiment, the printing medium with the recorded printing content is transported out from the paper output end B of the paper feeding channel S1 and enters the scanning channel S2 through the paper input end of the scanning channel S2, the scanning head 132 located in the scanning channel S2 scans and identifies the identification pattern on the printing medium to obtain corresponding information (e.g., the logistics information single number), and transmits the logistics information single number to the controller for storage and recording, so as to subsequently determine whether the logistics information single number has problems of wrong printing, missing printing, or repeated printing.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
