Abstract

The invention provides a printing control method, a device, a printer and a storage medium based on segmented printing, wherein the method comprises the steps of receiving data to be printed, and calculating the number of first printing segments required by the current printing point line according to the data to be printed and the printing parameters of the printer; the method comprises the steps of printing a current printing point row according to a first printing section number, calculating a second printing section number and a second motor rotating speed required by a next printing point row after printing is completed, adjusting the rotating speed of the motor according to the first printing section number and the second printing section number, and driving a printing medium according to the adjusted motor rotating speed to realize printing of the next printing point row. When the number of the first printing segments is larger than 1, if the number of the second printing segments is smaller than the number of the first printing segments, the motor is accelerated by smaller initial acceleration, so that the rotating speed of the motor is slowly increased to provide larger torque so as to overcome the adhesion resistance between the printing head and the printing medium, and the printing quality is improved.

Description

Printing control method and device based on segmented printing, printer and storage medium Technical Field The present invention relates to the field of printers, and in particular, to a print control method and apparatus based on segment printing, a printer, and a storage medium. Background Printers are widely used as a general computer output device in work, study, and life of people. Printers can be classified into laser printers, inkjet printers, thermal printers, etc. according to the principle of printing, among them, thermal printers are favored in terms of their high printing speed, convenient operation and maintenance, and affordable price. The thermal printer uses a thermal printing technology, and is characterized in that after the thermal printing head is heated, the thermal printing head is directly contacted with thermal printing paper, and chemical reaction is carried out at high temperature to change color so as to achieve the printing effect. For some thermal printers with low cost, because the adapter cannot provide high power, when the printing content of a line exceeds a certain point, the line of the point needs to be printed in a sectional printing mode, and the printing speed is reduced due to the sectional printing, so that the stay time of the line of the point is prolonged. Such as: The 4 inch printer 203 has 864 dots in total, that is, 864 dots are heated simultaneously when printing is performed in full line, 40mA is required for each dot heating, and thus the current is very high, and the cost is very high, so that the sectional printing is required to reduce the current implementation cost. The segmentation results in a reduced printing speed and a sticky paper. That is, if the time taken to print the line is X, if the line is not segmented, the line is changed to 2X by 2 segments, 3X by 3 segments, and 4X by 4 segments, 864 dots are divided into equal parts and heated, so that when the second segment is heated, the first segment is heated to cause adhesion of the paper to the TPH, especially when the label paper is sufficiently contacted with the TPH, the adhesive in the label paper is extruded and the TPH is smooth, so that when the current segment is heated, the cooling causes adhesion of the paper to the TPH. It is obvious that the more the number of the segments is, the larger the adhesive force is, so that when the next dot line is printed (the next dot line needs to be printed), the printing head and the paper are adhered and cannot be fed, and the phenomenon of printing compression is generated.
