Vertical and horizontal positioning
The horizontal positioning commands control the horizontal print positions of characters on the
receipt.
The commands describe operation for 80 mm paper. If the printer supports 82.5 mm paper, the dot
spacing is the same but there are 640 printable dots rather than 576 printable dots on the 80 mm paper.

Moves the print position to the next tab position set by the
set horizontal tab positions (1B 44 n1 n2 ... 00) command.
The print position is reset to column one after each line.
Tab treats the left margin as column one, therefore changes
to the left margin will move the tab positions.
When no tabs are defined to the right of the current
position, or if the next tab is past the right margin, line
feed is executed. HT has no effect in page mode.
Print initialization sets 32 tabs at column 9, 17, 25…
