[Samba] Non-registry problem: Slow printing

[ccaldwell at suscom-maine.net]

Greetings,

I have commented out the "wins support" line, restarted samba and
added the printer with the slow driver.  No difference in performance.
I also tried moving "wins" to the end of the name resolve order, also
no difference.

I'd rather not bring the Internet to a halt by sending around the 987k
log file, but those wishing to see it can go to:

Anyone have any thoughts?  --Chris

| It may have nothing to do with your printing problem, but you should 
| never have both "wins support" and "wins server" in the same smb.conf.  
| If this system is the WINS server, then use "wins support".  If another 
| system is the WINS server, then use "wins server".  This might be 
| significant since wins is listed first in "name resolve order" and a lot 
| of network printers now come with WINS support.
| 
| I don't know a thing about lprng printing (CUPS exclusively), so I can't 
| help you there.  The logs may be necessary.
