Note:
High-speed draft is available only with 10 cpi printing
(the printer’s default pitch). Also, the only print enhancement
that can be combined with high-speed draft is underlining. If
other enhancements or character sizes are selected, the printer
switches to normal draft speed. High-speed draft resumes
again after the feature is turned off.
Character pitch
Your printer’s default character pitch is 10 characters per inch
(cpi). However, you can select 12 cpi or proportional spacing
through your software or by sending printer commands.
In 10 and 12 cpi, each character gets an equal amount of space. In
proportional mode, however, spacing varies from character to
character. A narrow letter like the lowercase i receives less space
than the uppercase W. The width assigned to each character in
proportional spacing is shown in the proportional width table in
Appendix A.
The following printout compares the different types of spacing.
