-p Pitch
Sets the number of characters per inch. Typical values for Pitch
are 10 and 12. The actual pitch of the characters printed is also
affected by the values for the -K (condensed) flag and the -W
(double-wide) flag.
If you are printing an ASCII file on a PostScript printer, this
flag determines the character point size. You can specify positive
numbers greater than or equal to 1.
