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
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
LPRINT CHR$(27);CHR!$(87);CHR!§(l)
LPRINTCHR!§(27);“W”; CHR!$( 1)
For the following commands that use only 0 or 1 for the variable, either the ASCII codes 1 and 0 or the ASCII characters 1 and 0 can be used:
ESC s, ESC U, ESC x, ESC p, ESC W, ESC S,
For example, in BASIC you can turn on
LPRINTCHR$(27); “w”;CHR$( 1)
LPRINT CHR!$(27);“w”;“l”
