Other areas of potential conflict
In addition to the parallel port mode being set incorrectly, there may 
be other areas of potential parallel port conflict involving software and 
hardware from other manufacturers.The HP LaserJet 3100 product 
cannot share the parallel port with other peripherals. If none of the 
options in the Setup allow the HP LaserJet 3100 product to talk to the 
computer or you have other devices that need a parallel port, you can 
add an external ECP parallel port card to your computer. Then, 
connect the HP LaserJet 3100 product to one of the parallel ports and 
connect the other devices you have to the other parallel port. These 
parallel port cards are available at computer stores and will allow your 
HP LaserJet 3100 product to communicate with your computer 
without conflicting with other devices.
