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.
