EN Pitch Command 8-11
The following formula can be used to as a rule of thumb for computing
a maximum recommended pitch:
The character (“contour”) width in the above formula is expressed
as a percentage of an Em. For example, the width of characters in
Courier is very close to 60% of an Em, and .
(The width of characters in Letter Gothic is approximately 50% of an
Em. For other fonts, refer to the font metric data supplied by the font
vendor.)
Note If a scalable fixed-space font is selected using an ID number, send the
Pitch command to specify the size; otherwise, the size is determined
by the pitch characteristic value of the former font (as listed in the font
select table) See “Font Selection by ID Command” later in this
chapter for more information.
