The printer’s
high-
order control codes from 128 to 155 mirror
their low-order counterparts (O-27). In some cases it is necessary or
more convenient to use the high-order codes instead of the low-order
ones. For example, if your system will not send a 9 for a horizontal
tab, use 137 instead. For ready reference, both sets are listed here:
