It sounds like you are using the jetdirrect ethernet card.  Windows
has never been able to auto-detect this setup.  In XP, using the
wizard, select local printer and uncleck automatically detect.  Then
in the dropdown box create a new TCP/IP port using the printers IP
address and default settings.  Then manually select the HP LaserJet 4M
Plus driver.
This the the procedure I have used in the past.
