What are the real-world consequences of enabling kernel mode drivers on a
2003 print server?

I know how to do it I'm just wondering if it will cause problems.

Without going into details - the user mode drivers for the HP Color LaserJet
8500N provided by MS don't work well. We have three of these printers
attached to a 2000 server and need to move them to 2003 server.

MS Says that its a bad idea to use kernel-mode drivers. There are no
drivers from HP other than the kernel mode one we have been using on 2000
server (v4.3 dated 10-28-98). I've got 20 printers on this print server, 3
of which are this 8500N.
