[Samba] Non-registry problem: Slow printing

[ccaldwell at suscom-maine.net]

Greetings,

I have a client running samba-3.0.24 with mostly Windows-XP clients.
They can print to some printers (those with drivers provided by Microsoft)
without problem.

They can also print to printers with vendor supplied printer drivers
but they end up waiting up to 30 seconds just to select the printer.
There is a similar wait when adding the printer to the list of printers
the XP client knows about.

This does not appear to be the much discussed registry problem, as
we have repeatedly removed these registry entries and, though they come
back, there is no performance improvement.  Also, when people have
described the registry problem they have not said that it was driver
dependent.  Furthermore, as I understand the registry problem, it occurs
when there are non-existant printers listed ... which there are not in
our case.

There is no firewall between the client and the server except that which
Microsoft provides, and we still have the problem with that completely
disabled.

Here is my smb.conf:

    [global]
	    workgroup = FUZZBALL
	    netbios name = fzb3
	    netbios aliases = fzb3
	    server string =  fzb3
	    bind interfaces only = true
	    interfaces = eth0
	    null passwords = Yes
	    security = SHARE
	    guest account = guest
	    lanman auth = No
	    client lanman auth = No
	    client plaintext auth = No
	    socket options = TCP_NODELAY IPTOS_LOWDELAY 
	    local master = yes
	    prefered master = yes
	    log level = 3
	    log file = /usr/local/samba/log.%m
	    name resolve order = wins bcast host 
	    deadtime = 1
	    printcap cache time = 750

	    path = /var/tmp/samba%S
	    admin users = root, guest
	    printer admin = root, guest
	    guest ok = Yes
	    guest only = Yes
	    hosts allow = 10.1.0.0/10  127.0.0.1
	    hosts deny = 0.0.0.0/0 
	    printable = Yes
	    printing = lprng
	    print command = /usr/bin/lpr -Fl -r -P%p %s
	    lpq command = /bin/true
	    lprm command = /bin/true
	    lppause command = /bin/true
	    lpresume command = /bin/true
	    queuepause command = /bin/true
	    queueresume command = /bin/true
	    use client driver = Yes
	    show add printer wizard = no
	    disable spoolss = yes
	    max log size = 0

    [printers]

    [cr1000]
	    print command = lpr -Fl -r -P%p %s
	    comment = HPX,  Cole  0, C205
	    printer = cr1000
	    printable = yes
	    browseable = yes
	    guest ok = Yes
	    guest only = Yes
	    public = yes
	    writable = no
	    path = /var/spool/samba/cr1000

Does anybody have any ideas here?  The packet traces and samba log files
indicate that the PC is sending many transactions which are failing
but I am inexpert at decoding exactly what is wrong with them.  I can
include log files, but I am wondering if anyone knows of anything off the
top of their head?

All my web searches to date have revealed the registry issue but nothing
beyond that.

Thanks!  --Chris
