Gemini User's Manual
• •
PURPOSE:
Put printer in "offline" mode.
I
FORMAT:
DC3
I
CHR$(19}
REMARKS:
When this code is sent to the printer, Gemini
•
assumes the "offline" mode. All subsequent
characters and control codes sent to the
•
printer are disregarded. The only control code
that is processed is CHR$(17}(DC1}, which
•
cancels CHR$(19}, and puts the printer back
"on line:'
PURPOSE:
Activate the Gemini "buzzer?'
•
FORMAT:
BEL
•
CHR$(7}
REMARKS:
When the CHR$(7) code is sent to Gemini, the
•
result is that the built-in buzzer "beeps" for
one-fourth of a second. The buzzer function
•
can be temporarily deactivated by sending an
ESC "Y" 0 (CHR$(27) CHR$(89} CHR$(O) control
•
code) to the printer. After the ESC "Y" 0 code is
received, the CH R$(7} no longer causes the
•
buzzer to "beep:' The buzzer can be reactivated
by sending an ESC "Y" 1 (CHR$(27) CHR$(89}
•
CHR$(1} code} to the printer.
PURPOSE:
Allow printing even though the "paper-out"
•
detector indicates Gemini is out of paper.
•
FORMAT:
ESC "8"
CHR$(27} CHR$(56)
•
REMARKS:
When the ESC "8" function code is sent to
Gemini, the signal from the "paper-out" detector
•
is disregarded. This code allows you to print on
a single sheet. If the "paper-out" signal were
•
not disregarded, Gemini would stop printing
part way down the single sheet because the
printer would "think" it's out of paper. The
•
"paper-out" signal can be restored by sending
an ESC "9" function code (CHR$(27) CHR$(57}}.
