Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] figure 2 It is a schematic composition diagram of an embodiment of the printing device provided by the present invention. As shown in the figure, the double-sided printing device 10 includes a controller 11, a communication interface 12, a RAM memory 13, a FLASH memory 14, a first printing head 15, a second Two print heads 16, a cutter 17 and a detection unit 18. Among them, the controller 11 is used to control each module to perform work, for example, the controller 11 is used to control the communication interface 12 to receive the print data and various control instructions sent by the print request device (such as the host 30 or network equipment), wherein the print data It can be...

Abstract

The invention discloses a double-sided printing control method and device and a double-sided printer. The double-sided printing control method includes the steps that the length of printing data is calculated after the printing data are received; a first reference length and a second reference length are calculated; the printing data are divided into first data and second data, wherein the printing length of the first data corresponds to the first reference length, and the printing length of the second data corresponds to the second reference length; the first data are printed on a first side, and the second data are printed on a second side. By the adoption of the double-sided printing control method and device and the double-sided printer, the problem that in the correlation technique, paper is wasted when webs are used for double-sided printing is solved, and therefore the utilization rate of the second side of a medium can be increased, and the medium can be saved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a double-sided printing control method and device, and a double-sided printer. Background technique [0002] Double-sided printers that are used in supermarkets, shopping malls, etc. to print bills on roll continuous paper, which include a first print head and a second print head that are oppositely arranged, wherein the first print head is used to print on the first side of the medium (such as the front side) ) printing, the second printhead is used to print on the second side of the media (such as the back). This double-sided printer usually has two working modes. The first mode is that the print data received by the printer includes a data flag used to distinguish the first print data from the second print data before each line of print data, wherein the first print The data is printed on the first side of the medium by the first print head, and the second print data is printed on the...
