The Epic 880
TM
always prints at 203 dots per inch (dpi) and always uses the scalable
font to form characters. The resulting characters are not necessarily exactly the dot
size indicated, but are always spaced in a fixed dot cell provided that the legacy
commands are used. Adding or subtracting space between characters achieves
different character pitches with a fixed character cell size. As each dot has a fixed size
and position, only specific pitches are possible. The following table defines the fonts
and pitches possible with each.

Table 9. Possible Character Pitches
Character spacing may also be selected by requesting a print pitch based on
characters pre inch. Once again, the results are not exact in this case. The following
table lists the resulting spacing based on a given CPI request.
