Character Pitch
The Ithaca
®
8000 has 3 basic resident fonts, as well as downloadable fonts. The
smallest internal font is a 10 x 24 font and is typically printed in pitches from 16 to 20
characters per inch (CPI). The next larger font is 13 x 24, and is typically printed in
pitches from 14 to 16 CPI. The largest font is 15 x 24 and is typically printed in pitches
from 10 to 14 CPI.
The printer always prints at 203 dots per inch (dpi). Adding or subtracting space between
characters achieves different character pitches. 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.
