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

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

H e x a d e c i m a l : 1 B

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 W, ESC S, ESC s, ESC -, and ESC %
