Printer Communications
Your printer does not include a printer cable. The HP IEEE-1284-compliant
Parallel Interface Cable is best for your printer. Make sure the cable is
bidirectional—that is, that it allows two-way communication between your
printer and the computer. This type of cable allows you access to all your
printer’s features.
If you don’t know whether your printer cable is bidirectional, you can find
out by following these steps:
Ẅ
Make sure the printer cable is securely connected to both the printer and the
computer.
ẅ
Make sure both the printer and the computer are turned on.
Ẇ
Click the Printer Services tab of the HP Toolbox.
ẇ
Click Test printer communication.
The printer software tests the communication between your computer and your
printer and tells you if you have bidirectional communications.
If the cable is bidirectional, you should have access to all the features of your
HP DeskJet printer.
If the cable is not bidirectional, the printer might be unable to send messages to
the computer screen, but the printer will still be able to print.
At the time of publication, bidirectional communication was not available in
Windows NT 4.0.
Buttons and Lights
There are two buttons and three lights on the front of the printer. The lights
indicate when the printer is operating correctly or when it needs attention
from you. The buttons are used to control the printer.
Power Button and Light When lit the light indicates that the printer is
turned on.
Resume Button and Light Light blinks when there is a problem concerning
paper. Correct the problem and press the button.
Print Cartridge Light Blinks when there is a problem concerning a print
cartridge. Correct the problem. When the problem is
corrected and the top cover is closed, the light will
stop blinking.
If two or more lights blink at the same time, there is a printer problem. Correct the
problem and turn the printer off then back on again. See the Troubleshooting tab of
the HP Toolbox for solutions.
