Enhancing Your Printing; Using The Command Summary; Sending Printer Commands - Epson LQ-2550 User Manual

Using the Command Summary

The commands listed in the Command Summary in Chapter 8 consist of
various combinations of ASCII codes. You can use either the ASCII
characters or their decimal or hexadecimal equivalents. For example, the
command to turn on subscript is ESC
decimal format for this command is 27 83 01, and the hexadecimal
format is
1B 53 01.
In the Command Summary, commands are grouped by the printer
functions they control, such as character pitch, print enhancement, and
graphics. You can also look up commands in the list of software
commands in numerical order at the beginning of the Command
Summary. This list gives you page number references for the commands.
Some commands include a variable, such as the letter n. For example,
the command for selecting or cancelling double-high mode is ESC w n.
When n = 1, double-high mode is turned on, and when n = 0, it is
turned off. In the Command Summary, variables are printed in italics to
distinguish them from ASCII characters.
Sending printer commands from within your software program
How you format commands depends on the software program you are
using. Some software programs accept only the decimal format, while
others require certain punctuation. Some programs don't let you insert
printer commands at all.
If your software does allow you to send commands to the printer, use the
Command Summary to find the command you want to send. Your
software manual should explain exactly what format and punctuation
are required.
