PRINTER COMMUNICATIONS

Your printer does not include a printer cable. The HP IEEE-1284 Com- pliant 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:

1Make sure the printer cable is securely connected to both the printer and the computer.

2Make sure both the printer and the computer are turned on.

3Click the Printer Services tab of the HP Toolbox.

4Click 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 720C Series 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.

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 indicates that the printer is

 

turned on.

Resume Button and 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.
