So your problem is to figure out what code you want to use, no
matter what it is called. You may find that this can be quite a problem.
Your computer's manual may say to use ASCII 10 while your spread-
sheet program recommends a
are both talking about the same code.
This manual tells you the different names for the same code.
Appendix A gives a complete summary of all the control codes (also
called commands). Appendix E contains a conversion chart for all the
common names for the ASCII codes.
Some of the LQ-1500's functions are controlled by codes consisting
of one character. These are the ASCII codes with decimal values
between 1 and 31, and are the codes that you can type by holding the
control key while you press a letter key. For example, the code ASCII
is the same as

Of course the LQ-1500 has many more than 31 functions. To use the
many additional functions, you use one special code to enable all the
control codes that consist of more than one character. This code is
called Escape, and in this manual it is abbreviated as <ESC> . You will
use this code often with the LQ-1500 because it allows you to use the
many features of the printer.
Here is an example of how the escape code is used. It may seem
tricky at first, but follow along and you'll soon understand. The code
to turn on the italic print function is <ESC>

abbreviations for their names. In these cases we use the abbreviations.
<ESC>q is the abbreviation for escape, which is also ASCII
Therefore, the <ESC> "4" that turns on italic print actually is ASCII
