Command Summary

Sending printer commands

Most actions your printer performs are handled by your software.
Software commands instruct the printer to print in a particular typeface,
feed the paper a certain amount after printing each line, start printing a
particular place on the page, and so on.
Some software programs let you send these commands yourself. The
commands your printer recognizes are listed in this command summary.
How you format commands depends on the software you are using. Some
software programs accept only the decimal format, while others let you
type in ASCII characters. (Some programs don't let you insert printer
commands at all.) In addition, your software probably specifies certain
punctuation you must use to enter the command. If your software allows
you to send commands to the printer, the software manual should explain
exactly what format and punctuation are required.

Using the command summary

The following section lists and describes all the commands by topic. If a
command has no parameters, it is merely listed. If it has parameters, they
are explained. The parameters are indicated by lowercase italicized letters,
usually n. The examples below show how the parameters are indicated.
