Note: High-speed draft is available only with 10 cpi printing.
Underlining and double-width printing can be combined with
high-speed draft. If other enhancements or character spacings are
selected, the printer switches to normal draft speed. High-speed
draft resumes again after the feature is turned off.
Character Spacing
To add greater variety to your documents, the printer has three cpi
spacings, as well as proportional spacing. Each one can be selected
with a software command.
For each of the Letter Quality fonts (Roman and Sans Serif), you can
choose a character spacing of 10, 12, or 15 cpi, or proportional
spacing. However, you cannot combine normal draft mode with
proportional spacing, and high-speed draft mode is available only
in 10 cpi printing.
The printout below compares the three spacings:
As shown above, 15 cpi characters are only about two-thirds the
height of 10 and 12 cpi characters. This makes 15 cpi particularly
useful when you want to separate certain material from the main
text.
In fixed cpi spacing each character is given the same amount of
space. The width of proportional characters, however, varies from
character to character. For example, a narrow letter like i takes less
space than a wide letter like W. The width of each proportional
character is given in the Appendix.
