The simplest type of command consists of a single character to be
sent to the printer. For instance, to print in condensed mode the
code format is:
ASCII code: SI
Decimal:
15
Hexadecimal: 0F
This code can be sent from a program by sending the code 15
directly.
More complex commands consist of two or more character codes.
For example, to print in double-wide mode the code format is the
following:
ASCII code: ESC W n
Decimal: 27 87 n
Hexadecimal: 1B 57 n
In this case n can be either 1 or 0, to begin or end double-wide
printing. You can use either of the following commands to turn
ON double-wide print from BASIC:
LPRINT CHR$(27);CHR$(87);CHR$(l)
LPRINT CHR$(27);“W”;CHR$(l)
For the following commands that use only 0 or 1 for the variable,
either the decimal or hexadecimal values 1 and 0 or the ASCII
characters 1 and 0 can be used:
ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, and ESC %
For example, in BASIC you can turn on proportional spacing with
either of these statements:
LPRINT CHR$(27);“p”;CHR$(1)
LPRINT CHR$(27);“p”;“1”
