• If you still encounter communication problems after verifying that the
parallel port is configured for bidirectional communication, there might
be a conflict with other software your computer. Because the HP
LaserJet Companion shares the parallel port with printers and other
devices, software that uses these devices must occasionally release the
parallel port to allow other programs to use the port. If a program that
uses the parallel port does not release it, then the HP LaserJet
Companion software will be unable to communicate with the HP
LaserJet Companion. Printer drivers and printer status monitors are
automatically loaded by Windows at startup, and are often the cause of
such conflicts. The README.TXT, which shipped with the HP LaserJet
Companion, contains a list of software known to cause conflicts. For
instructions on disabling conflicting software, see the HP LaserJet
Companion README.TXT file located in the PaperPort Program group.
