PCL Printer Command Syntax
Before using printer commands, compare these characters:
Lowercase l: | l | Uppercase O: | O |
Number one: | 1 | Number 0: | 0 |
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 E-1 displays the elements of a typical printer command (in this instance a command for page orientation).
