I've been running into a few problems with clients running Windows 2000 for quite a while now when it comes to printing to large format printers (HP 755CM & HP 3800CP). When it came to large jobs hitting around 200mb+ postscript files (varied between users), they would get errors all the time. These errors occured for the standard HP Postscript driver for the DesignJet 755CM, the HP driver for the Fiery X2 attached to the DesignJet 3800CP, and now even for the PosterJet driver for their RIP engine (replaced the Fiery). These errors happen from almost any product that can print to these drivers (Photoshop, Geomedia).
However, my Windows XP setup on my client prints flawlessly to these same devices. I finally found some time to test some setups in a controlled setting:

Program: Adobe PhotoShop 6.0
File: 259 mb .psd file (24" x 20" @ 400 ppi)
Printing to PosterJet RIP for HP DJ3000/3800 CP - (able to preview the RIP)

My machine:
Dell Precision 530 / 1.4 Ghz P4 Zeon / 512 RDRAM
WinXP with all critical updates/SP1 installed
pagefile max size set to 1.2 GB
scratch disk on different partition with 4GB free

Postscript file size printing to PosterJet - 605mb, no errors printing through network

Test Box (try #1):
Dell Optiplex GX260 / 2.8 Ghz P4 / 1024 DDRRAM
Win 2000 with all critical updates/SP3 installed
pagefile max size set to 2.5 GB
scratch disk with 20GB free space

Postscript file size printing to PosterJet - 180mb, will not RIP

Test Box (try #2):
Same hardware as above, but changed to WinXP with all critical updates and SP1 installed

Postscript file size printing to PosterJet:
  - 605mb, no errors when printing to a local install of PosterJet Printer but get errors when printing through network even though it spools up to size.

I then installed Office XP without any updates:
  - 605mb, no errors printing through network

I've seen similar posts in the Photoshop forum with people with Win2K having issues...I don't think it's a driver issue, but more of an OS issue.

Has anyone else encountered/duplicate this?
