Using the Command Summary
Note: Some application programs can use control key sequences.
See the Control key chart on page 9-4 for information on using
these.
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: OF
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: IB 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$(2T);CHR$(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 W, ESC S, ESC s, ESC -, and ESC %
