No parallel port is
available or the
parallel port is
being shared by
another device. The HP LaserJet 3150 product might
need to be directly connected to the
computer’s parallel port. It might not be
able to share the parallel port with another
device. If you have a device such as an external
disk drive or switch box connected to the
parallel port try unhooking it and
connecting the product directly to the
computer parallel port. If it works and you
want to continue using both devices, you
must get two parallel ports on your
computer.

Check that all cords are plugged in at the
HP LaserJet 3150 product and the
computer and that they are plugged into a

then reinserting it. If the
Ready message is

time on the computer. Do not perform I/O
or processor-intensive tasks (such as
sending a fax or playing a video game) on
the computer while printing.
Free disk space or defragment the hard
drive. See the computer documentation
for help.
