[Samba] printing totally broken

[Nathan Vidican]

Had a similar, if not identical problem on our network too. Wasn't so much a
problem with samba though.

Turned out to be a resolution issue between CUPS and any network print
servers (mostly built-in or external HP Jet Direct Units). Seems CUPS wants
a hostname to resolve one way or another to an IP address, we did manage to
fix the problem relatively easily at that.

We simply gave each of the printer servers on the network a legit hostname
and associated reverse dns entry as well and the delay pretty much
disappeared. Seems the HP units in particular (by default too) have various
protocols enabled, and reply using their own 'default' hostnames on the
network ... If no actual mapping for this hostname exists, then huge
communication delays occur between cups and the jet directs, which in turn
seemed to delay samba from requests to/from the queue... Like I said though,
simple DNS records did solve it - may or may not be the same for yourself,
but worth looking at nonetheless.

Hi All,

I have a serious problem with my Samba printing.  Basically, it is totally
broken.  The symptoms include client machines waiting forever for a print
dialog to appear, especially Win2k machines, and a complete inability to
get a properties dialog reliably.  I run Samba 3.0.14a + OpenLDAP 2.2.24 on
Solaris 8 on a V880.  My smb.conf is as below.  Any advice would be
appreciated.
