Thermal transfer printer with ribbon saving function

Abstract

The present invention relates to a thermal transfer printer and especially to the thermal transfer printer with ribbon saving function. The thermal transfer printer comprises a paper feeding device of printer, a printing head, and a ribbon transmission device which is controlled differently from the paper feeding device of printer. The printing head is controlled by a printing head clamping device which comprises a detecting module that is used for detecting the printing position. The printing head clamping device is controlled by software for clamping when the printing positioned is detected by the detecting module. The ribbon is controlled by the ribbon transmission device for synchronously moving the printing paper for starting printing. When the printing is completed, the software makes the printing head clamping device loosen for breaking away from the printing paper. Simultaneously the ribbon transmission device stops the transmission of ribbon so that the ribbon does not move together with the printing paper. The thermal transfer printer of the invention has the beneficial effects of remarkably reduced wastage of ribbon, accurate printing of content which requires printing, no wastage to the blank part, and suitability for the requirement of environment protection and saving.

Description

technical field [0001] The invention relates to a thermal transfer printer, in particular to a thermal transfer printer with the function of saving carbon ribbon. Background technique [0002] At present, ordinary label printers are all installed with printing paper and carbon ribbon, and the print head is pressed down and clamped manually. When printing, the printing media such as printing paper and the ribbon move synchronously. When the printing is completed, no matter how much you print on the label, the ribbon of one label width will not be used anymore and will be wasted. Since most of the label printers use the ribbon and the label together, for users who print less content on the label, the amount of wasted ribbon is astonishing, especially for the labels that are printed in sets, the waste is several times To ten times as much. With the continuous development of society, there are more and more equipment for printing labels, so more and more carbon ribbons are was...
