Can't print to XP printer from Fedora - SAMBA problem?

["Arch Willingham" <arch tuparks com>]

I created a link from a Fedora laptop to an XP pro machine. I can use SAMBA to read the drives with no problem. I tried creating a printer. I opened the crate printer GUI (in gnome) as follows:

description="printer"
location="CAR"
device uri="smb://...................../CAR/hpoffice" (hpoffice is the name of the actual print share)
Make and model="HP OfficeJet 5500 Foomatic/hpijs (recommended)"

If I click CHANGE on Device uri , it pops up with an authentication box. I put in my XP user name in the form of DOMAINNAME/USERNAME and my password and click verify...it says all is OK. If I then go to the test print page, it acts like it prints. If I go to the XP machine, I see errors where it appears that SAMBA is trying to log in with the username "lp" and no domain.
Any ideas?

Thanks!
