Understanding PCL Printer Command
Syntax
Before using printer commands, compare these characters:
Many printer commands use the lowercase letter l (
l
) and the
number one (
1
), or the uppercase letter O (
O
) and the number zero
(
0
). These characters may not appear on your screen as shown
here. You must use the exact character and case specified for PCL
printer commands.
Figure D-1 displays the elements of a typical printer command (in
this instance, a command for page orientation).
