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: 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$(1)
For the following commands that use only 0 or 1 for the variable, either
the ASCII codes 1 and 0 or the ASCII characters 1 and 0 can be used:
ESC s, ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, ESC w, and
ESC %
For example, in BASIC you can turn on double-high with either of these
statements:
LPRINT CHR$(27); “w”; CHR$(1)
LPRINT CHR$(27);“w”;“l”
8-2
