Description

Technical Field

[0001] The utility model belongs to the technical field of printers and relates to a print head side-flip type label printer. Background Art

[0002] A label printer is a device that prints information on a label. When printing, the print head is pressed against the print roller, and the label and the carbon ribbon pass between the print head and the print roller. The movement drives the print roller to rotate to realize the printing process. The carbon ribbon and print paper roll of the existing label printer are independent consumables. Since independent carbon ribbon and print paper are required, the existing printer is difficult to assemble, has a large size, and is inconvenient to use. Utility Model Content
