All three formats are equivalent, and it should be easy to pick the
one most suited to your purpose.
The simplest type of command consists of a single character to be
sent to the printer. For instance, to advance to the next horizontal tab
stop the code format is:
ASCII code:
H T
Decimal: 9
Hexadecimal: 09
This code can be sent from a program by sending the code 9 directly.
More complex commands consist of two or more character codes. For
example, to print in proportional mode the code format is the
following:
ASCII code:
ESC p
n
Decimal:
27 112 n
Hexadecimal:
70
n
In this case n can be either 1 or 0, to begin or end proportional printing.
You can use either of the following commands to turn ON proportional
print from BASIC:
LPRINT
LPRINT
Note
In the format section letters such as n and d represent variables that
must be entered when the command is used. These variables should be
entered as ASCII codes, not characters. For example, the format for
selecting an international character set is ESC R n. To select the French
character set, the variable n should be 1. In BASIC the command to
select the French character set is LPRINT
