Samba 2.2.7 printer problems

[Andy Kowal]

Hi,
I have problem with printing with Samba 2.7.7. I have Red Hat 7.3 kernel 2.4.18-3. My smb.cnf was working fine until I have upgraded Samba to 2.7.7, right now printer is not working properly, but I did not change anything . Following message is appeared:
[2003/02/13 11:59:11, 7] param/loadparm.c:lp_servicenumber(3594)
  lp_servicenumber: couldn't find printers

Full log.smdb with my samba configuration and error is:

[2003/02/13 11:59:11, 0] smbd/server.c:main(707)
  smbd version 2.2.7 started.
