ON LINE
The ON LINE button sets the printer on-line and off-line. The status changes
each time you press the button.
When the printer is on-line, it can receive and print data from the computer
and will be indicated by the ON LINE indicator being lit. When the printer is
off-line, it stops printing and sends the computer a signal indicating that it
cannot accept data.
The printer powers up in the on-line status when paper is loaded. If paper is
not loaded, the printer powers up off-line with the POWER indicator light
blinking. When you load paper, the printer goes on-line.
You will want to press the ON LINE button:
• Before and after any other panel operation
The other panel buttons operate only in the off-line state. Press the ON LINE
button to go off-line. After performing the panel operation(s), press the ON
LINE button again to go back on-line.
• To pause during printing
If you press the ON LINE button during printing, the printer stops printing
and goes off-line, allowing you to check the printout or change a control
panel setting. Printing resumes when you press the ON LINE button again
to go back on-line.
PAPER FEED
If you press and release this button while off-line, the paper will feed forward
one line. If you hold the button down, the printer will perform consecutive
line feeds.
If you also press the ON LINE button while you are line-feeding, the paper
will feed automatically to the top of the next page. This is explained later.
If you press the PAPER FEED button while on-line, this will alternately
select and cancel the Quiet mode. When in Quiet mode, the printer will print
slightly slower, but at a reduced noise level.
