Interpreting PCL Printer Command Syntax

Before using printer commands, compare the following characters:

	Lowercase L:	l	Uppercase O:	O
	Number one:	1	Number zero:	0
Note	You must use the exact character and case specified for PCL printer
	commands.

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.

Figure B-1 shows the elements of a typical printer command (in this example, a command for page orientation).
