Understanding 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.
The following illustration displays the elements of a typical printer command (in this instance, a command for page orientation).
