Print position
The print position is the standard position for printing characters, bitmaps, and bar codes.
There is a horizontal print position and vertical print position, which are the reference points
for vertical position movement and horizontal position movement.
Characters are arranged with their top edges aligned with the print position.
The baseline of each character is the bottom edge of the character, regardless of size, font,
etc.
