Slow Printing (2nd Attempt)

( I thought I sent this message out before, but never saw it in the digests )
Windows NT 4.0 clients printing to Samba 1.9.18p8 running on Solaris
2.6/2.51 machines. The Samba servers are setup like this :
security = server
password server = %m
encrypt passwords = yes
networkstation user login = no
So the server uses the client as the password server.
Bringing up a print dialog from any application on the NT clients, or
bringing up the properties dialog for any printer takes between 10 to
30 seconds or more.
A debug run at level 10 shows the client and server doing the
authentication chat. I've also just noticed that the server
also runs the 'lpq command' for each printer the client has installed
whenever I open the "Printers" folder on the client, or whenever I
attempt to print/get properties of any one of the printers.
I would guess that is adding to the slow response if not being the
sole cause of it.
Is this expected behavior ? Is there a way to tune this ? Is the
'lpq command' supposed to run for all printers each time I open the
"Printers" folder ?
Or is it the authentication chat that is taking so long ?
Any tips/pointers/help/patches are greatly appreciated.
