The current printer generally prints in full scan. [0004] For example, the Chinese patent with the application number CN201620419101.7 discloses a printing head moving device of a label printing machine; the slider is inserted into t...

AI Technical Summary

Problems solved by technology

[0006] 1. Printers generally print in full scan mode, which wastes the printing efficiency of the printing machine;

[0007] 2. When the printing device moves up and down, there is a lack of protective devices, which cannot avoid the lateral displacement of the printing device when it moves up and down;

[0008] 3. The rotation of the screw rod has a limited distance to the left and right movement of the sliding sleeve, which cannot improve the overall displacement of the printing device
