When you turn on your printer, its tab stops are automatically set for every eight columns. Each
time you send the tab character (HT), the printhead moves eight columns to the right before
printing the next character.

This command lets you set horizontal tab stops at specific columns on the page. As with
margins, the actual position of the stops depends on the pitch you’re using, and won’t change if
you switch to a different character width. Be sure to give the stops in ascending order. After you
have specified all the stops, end the sequence with a NUL character (use CHR$(0) in BASIC).
If you send the command as ESC D NUL, with no stops specified, all horizontal tab stops will
be cleared, including the 8-column default stops. Turning the printer off and on again restores
the printer's default tab stops.
