When printing labels with the TSC MH641, it is found that the printing heights on the left and right are inconsistent.

This issue is caused by the incorrect adjustment of the printer head position, 

Solution: Adjust the screws on the printhead using a 5mm hex (Allen) wrench.

Turn the screw clockwise to move the print on the right side upward, and counterclockwise to move it downward.

The same adjustment principle applies to the left side.
