Problems solved by technology

[0003] During the use of the printer, it is necessary to use the print head to heat the carbon ribbon and leave a mark on the printing paper. In the traditional dual-channel printer, two rolls of printing paper can be placed at the same time, which improves the continuous working ability of the printer. However, due to the defects of traditional dual-channel printers, it will cause waste of carbon ribbons and increase the cost of use

Embodiment 1

[0046] like figure 1 and figure 2 As shown, the printer includes a paper feeding part 100 and a printing part 200, a first paper feeding passage 300 is formed between the paper feeding part 100 and the printing part 200, and a printing roller 110 is provided on the side of the paper feeding part 100 close to the printing part 200, and the printing The printing head 210 that is arranged opposite to the printing roller 110 is provided on the part 200, and the printing channel 400 is formed between the printing roller 110 and the printing head 210. 1. The second paper-feeding path 120 is connected with the printing path 400, and the paper-feeding part 100 includes a first driving mechanism, and the first driving mechanism is used to respectively drive the printing paper 10 in the first paper-feeding path 300 or the second paper-feeding path 120 To move, the printing unit 200 includes a second driving mechanism 220 , the second driving mechanism 220 is used to drive the carbon r...

Embodiment 2

[0072] The difference between the printer described in Embodiment 2 and the printer described in Embodiment 1 lies in:

[0073] Such as Figure 9 As shown, the second rotating assembly 222 also includes a third motor 2221f and a third transmission shaft, the first rotating assembly 221 also includes a fourth transmission shaft, and the third transmission shaft passes through the first mounting plate 231 and the second clamping plate in turn. 2221a, the second friction plate 2221b and the second fitting 2221c, the third transmission shaft is rotatably matched with the first mounting plate 231, the second friction plate 2221b and the second fitting 2221c, the third transmission shaft and the second clamping disc 2221a, the third transmission shaft is connected to the third motor 2221f, and the fourth transmission shaft passes through the first mounting plate 231, the first clamping disc 2211a, the first friction plate 2211b and the first fitting 2211c in sequence, and the fourth...

Abstract

The invention discloses a printer and a printer control method. A first driving mechanism drives first printing paper to retract back, the first printing paper retracts back into a first paper walkingchannel from a printing channel, and a second driving mechanism drives a thermal transfer ribbon to retract back together with the first printing paper synchronously; and the first driving mechanismdrives second printing paper to advance, so that the second printing paper advances to enter the printing channel from a second paper walking channel, and the second driving mechanism drives the thermal transfer ribbon to advance together with the second printing paper synchronously. By means of the above printer and the printer control method, the thermal transfer ribbon is subjected to the process of retracting and advancing again, the part, which has not been printed, on the thermal transfer ribbon cannot extend out of the printing channel, and waste of the printing paper can be avoided.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printer and a printer control method. Background technique [0002] The usage rate of printers in office, cashier and other scenarios is very high, which facilitates people's work. [0003] During the use of the printer, it is necessary to use the print head to heat the carbon ribbon and leave a mark on the printing paper. In the traditional dual-channel printer, two rolls of printing paper can be placed at the same time, which improves the continuous working ability of the printer. However, due to the defects of the traditional two-channel printer, it will cause waste of carbon ribbon and increase the cost of use. Contents of the invention [0004] Based on this, the present invention overcomes the defects of the prior art, and provides a printer and a printer control method with low usage cost. [0005] Its technical scheme is as follows: [0006] A printer, c...
