[SLE] CUPS and Samba problems

Hello! I have Samsung laser printer, which is connected over USB to PC with Suse 10.0. There was a CD with printer, which also included support for linux, so i`ve installed included LPP (linux printing package) which has added the printer. The test page prints perfectly. Then i set up Samba with intention that the win users could also use printer overt the network. The problem is that when i try to use printer in WinXP i get "access denied" error although the printer is installed over "connect" option in win. I can also browse some samba shared folders. I have added the same user as it is in winxp to linux and also samba. What I am forgeting? Thanks for the hints. Scorpy
