Using The Command Summary - Epson FX-870 User Manual

Using the Command Summary

The following sections list and describe all the commands available
in the Epson ESC/P and the IBM emulation modes. They are sorted
by topic in each mode.
If a command has parameters, they are explained. Parameters are
indicated by lowercase letters, usually n. The examples below show
how the parameters are indicated.
ESC @ is a command with no parameters.
ESC U 1 /0 is a command that uses 1 to turn the feature on and 0 to
turn it off.
ESC $ nl n2 is a command with two parameters.
ESC D nn is a command with a variable number of parameters.
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 on a particular place on the page, and so on.
Some software programs let you send these commands yourself.
This allows you to enhance your text in ways that may not normally
be available through the software. For example, some word
processing programs do not offer italics, but by inserting a
command in your document, you can use italics anywhere you like.
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.
