Hello! Help please

1)i have:
CentOS 5.2 final
Samba 3.0.28-0.e15.8
Cups 1.2.4-11.18.el5
90 printers connected to cups by lpd/lpr and samba shared with installed
windows drivers using rpcclient.

When windows clients press "CTRL+P" from any aplication (windows notepad,
Word), window appears which shows list of printers, connected to client from
my samba server. After i click on the printer an about 10 seconds long delay
occurs. And then printing ok. But 10 second - too long.

But if user belongs to group ("Domain admins" in this case) which specified
as admin users in smb.conf (admin users = '@Domain Admins'), delay does not
occurs! (1-2 seconds).

Logs indicates no errors.
Samba using LDAP which installed on remote host.

3)smb.conf, cupsd.conf, ldap.conf
