Step 6: Install printer software
Before you can use your new HP DeskJet printer, you must
install the printer software on the computer from which you will
print. Your printer software is located on the CD included with
your printer.
From time to time, Hewlett-Packard provides updated printer
software. Go to “Printer Software” on page 50 for information
on obtaining updated printer software.
Before You Begin
1 Make sure the computer is fully set up and operational.
2 Make sure that the printer is properly set up and ready to
print using the instructions provided earlier.
3 Make sure that the printer is connected to the computer with
a parallel printer cable and that no peripheral devices (such
as scanners, backup units, and switch boxes) are installed
between the printer and the computer.
4 Make sure both the printer and the computer are turned on.
5 Close any software programs that are open and running on
the computer, except the HP DeskJet installer, Windows
Explorer, or Program Manager. See page 22 for instructions
on how to close software programs.
Note: If the Resume light continues to blink or if the
cradle doesn’t move to the right side of the printer, take
out both cartridges and reinsert them.
When a print cartridge starts to run out of ink, replace it. If
you do not have a replacement, leave the empty print
cartridge in the cradle of the printer. The printer will not
print with only one print cartridge installed.
We recommend you keep spare print cartridges on hand.
When buying print cartridges, check the part numbers
referenced below carefully to make sure you are buying
the right print cartridges for your printer. These print
cartridges have been specifically designed to work with
your printer to produce results that are always clear,
always sharp.
