RFID label printing method, printing method, device and label printer of label printer

Abstract

The invention discloses a label printer RFID label printing method, a printing method and device and a label printer. The RFID label printing method comprises steps that the height of each to-be-printed label paper in each roll of label paper, the spacing between two adjacent sheets of to-be-printed label paper and the region length of the reading / writing region of an RFID reader / writer are pre-acquired; the reading / writing region R of each to-be-printed label paper is acquired according to the height of each to-be-printed label paper, the spacing between two adjacent sheets of to-be-printed label paper and the region length of the reading / writing region of the RFID reader / writer, and a distance R1 between the end position of the reading / writing region R of each to-be-printed label paper and the start position SL of the reading / writing region R of a subsequent to-be-printed label paper is greater than the region length of the reading / writing region of the RFID reader / writer; whether the reading / writing region R of the to-be-printed label paper completely can reach the reading / writing region read by the RFID reader / writer is determined; if yes, invisible data is written in the present to-be-printed label paper.

Description

technical field [0001] The invention relates to an RFID label printing method of a label printer, a printing method, a device and a label printer. Background technique [0002] The label printer is a kind of label printer that does not need to be connected to a computer. It has its own input keyboard or smart touch screen operation. It has built-in certain fonts, fonts and a considerable number of label template formats. Users can directly customize according to their needs through the LCD screen or APP software. It is a printer for inputting, editing, and typesetting the label content, and then directly printing out the label. The printing methods of current label printers include visible data printing and invisible data printing (such as RFID label printing). The visible data printing refers to embodying text and / or graphics on the label paper. The invisible data printing refers to An RFID antenna is set on each label paper, and an RFID reader is set on the label paper ou...

Problems solved by technology

The disadvantages are: 1. If the height of the label paper is less than the distance between the print head and the reader, when the RFID reader reads and writes the current label paper, the last label paper has passed the print head. It can be seen that the data is printed on the next label paper, and the next label paper needs to be returned to the position of the print head after the reading and writing of the previous label paper is completed; 2. If the height of the label paper is greater than that of the print head and the When the distance between the readers is different, after the visible data of the higher label paper is printed, the RFID antenna on the higher label paper may have already passed the RFID reader, so it is also necessary to use The higher label paper retreats so that the RFID reader can write invisible data into the higher label paper

The disadvantage is: because the invisible data is written into the label paper first, and then the label paper after the successful reading and writing is visible printed, during the visible printing, the pressure of the rubber roller and before printing may cause damage to the RFID chip of the label, which in turn leads to Users cannot identify damaged label stock
