Number one:

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).
