smb_panic when adding printer

Hi there,

I'm in the process of building up a new RedHat Linux Server for my
company, to be used as a file and print server. I've got most of the
way through it, but I'm having trouble setting up the printing share.
I can share the printer, and print from a windows client BUT, only if
I install the driver manually from the driver CD. I need to set it up
so that the user can just browse to the server, double-click on the
printer, and bang, it's all installed, so they need to be able to
download the driver from the server.
I've done a bit of searching, and found that I needed to set up a
[print$] share, which I have done. I get most of the way through
adding a printer driver (to the point where the files are copied to
the server), then it fails and returns the message: "Unable to install
Lexmark Optra C710 PS3, Windows NT 4.0 or 2000, Intel. Operation could
not be completed". It then just prompts me to do it all over again.
This same message happens for all printers I've tried (Different
driver name obviously). The log file is giving me smb_panic Internal
Server Error.

I'm stumped. I've been searching around for days trying to find
something on this, through docs, mailing list archives, anything, but
nothing has helped. Any help would be greatly appreciated. Included is
my smb.conf file, so you can see what I've got, as well as the extract
of the logs where I'm getting said error.
