[Samba] Problems printing from Windows 2000

[Des Dougan]

I run a small network at home, with a Linux server, which shares files
and a printer. I also have a Linux PC (RH 9, KDE 3.1, CUPS 1.1.17) from
which I am trying to share a Lexmark 3200 inkjet.

Samba (2.2.7a-security-rollup-fix) seems to be generally configured OK -
I can print to the Lexmark from a Windows 98 system, and from another PC
running Mandrake 9.1. However, I am unable to print from two Windows
2000 PCs. I can see the printer, view its properties (although I can't
change any). However, any time I try to print, it spools 96 bytes and
then the PC goes to 100% CPU and requires to be restarted. 

I have been working on the assumption that it is a security/rights
problem, but I've exhausted all the various checks I have researched.

Can anyone shed any light on what might be happening here?
