Special Print Modes
•
PURPOSE:
Print characters in double-strike printing mode.
I
FORMAT:
ESC "G"
CHR$(27) CHR$(71)
•
REMARKS:
When the ESC "G" code is transmitted to the
printer, subsequent characters are printed in
I
the double-strike mode. The double strike is
cancelled when the ESC "H" code is sent to
•
the printer - CHR$(27) CHR$(72). When in
double strike, the characters are printed once,
•
then the paper is moved up 1/144 inch and the
characters are reprinted. Shifting in and out of
•
double-strike on the same line will cause the
line to slant slightly. The double-printing mode
I
can be used with any other print-style
commands.
EXAMPLE:
LPRINT CHR$(27);"G";
I
"This is double-strike print"
LPRINT CHR$(27);'H";
I
"This is standard print"
PURPOSE:
Print in emphasized printing mode.
