Changing horizontal pitch changes the physical
tab positions .
Changing between standard and expanded print
does not affect the tab positions.

5.3.5 Horizontal Pitch Escape Sequences
Character pitches of 5, 6, 8-1/3, 10, 12, and
16-2/3 characters-per-inch are available. Pitches
5, 6, and 8-1/3 are double-wide versions of stan-
dard pitches 10, 12, and 16-2/3. Characters at 10
and 12 cpi can be enhanced and so can charac-
ters at 5 and 6 cpi. See Table 5-8 and 5-9.
