Using the Command Summary
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
H e x a d e c i m a l : 0 F
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 (on) or 0 (off), 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$(l)
LPRINT CHRS(27);"p";"l"
