Note:
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.
