Character Pitch
Important!
Front panel settings for character pitch are normally
overridden by software commands.
Character pitch determines how many characters will print on
each line. You can choose a specific fixed width for each
character of from 10 to 20 characters per inch (CPI). The
higher cpi settings are often used for spreadsheets.
In LQ mode, you can select proportional (PROP) which sets
character widths based on the character itself: e.g., the letter i is
assigned a narrower width than the letter m. This provides a
more polished, typeset appearance.
Set the character pitch by pressing CHARACTER PITCH/RESET
(1) until the LED beside the desired setting glows.
