samba - May 2008 - Got cupsaddsmb working but the client PC download of the printer drivers fails for 3 out 4 PCs tested so far!

I have built a new CUPS print server on Ubuntu 8.04 server for our
office (used apt-get to download the CUPS v 1.3.7 and Samba v3.0.28a
packages) as a replacement for our existing Suse CUPS print server and I
want to use the cupsaddsmb tool to set up printer drivers for download
by PCs rather than using the Add Printer Wizard method which we have
used on our older CUPS print server.

After some research I eventually got cupsaddsmb to work.


Now we are testing the new CUPS print server.

So far we have tested it using 4 Windows XP PCs and we have a problem in
that 3 fail when they do a connect to our 'r4secrxerox8560' printer in
the printer share window with the output of the following error during
the download of the printer drivers:

"The server for the 'r4secrxerox8560' printer does not have the
correct
printer driver installed. If you ...".

Strangely this works fine for one of the PCs!


Can anyone help me resolve this error?


BTW, I have documented below the steps that I carried out in trying to
get the new CUPS print server and cupsaddsmb to work in case there is a
problem with the way I have done it.



Thanks

Steps in trying to get the new CUPS print server and cupsaddsmb to work:

1) Modified the /etc/cups/cupsd.conf file so that I can access the CUPS
server from my PC (both are on different office subnets but I can now
access the CUPS server OK from my PC).


2) Created a Samba password for root using the smbpasswd tool.


3) Downloaded the CUPS PostScript driver file,
cups-windows-6.0-source.tar.gz, from the
http://www.cups.org/windows/software.php?6.0 web page. This file
extracted to a cups-windows-6.0 folder and in the i386 sub-folder were
the files:

    cups6.inf
    cups6.ini
    cups6.ppd
    cupsps6.dll
    cupsui6.dll


4) Located the XP Windows driver files on my PC (these were all
uppercase filenames and had to be changed to lowercase):

    ps5ui.dll    (from C:\Windows\system32\spool\drivers\w32x86\3
folder)
    pscript.hlp  (from C:\Windows\system32\spool\drivers\w32x86\3
folder)
    pscript.ntf  (from C:\Windows\system32\spool\drivers\w32x86\3
folder)
    pscript5.dll (from C:\Windows\system32\spool\drivers\w32x86 folder)


5) Copied all the files mentioned in steps 3 & 4 above to the
/usr/share/cups/drivers directory on the new CUPS print server.


6) Modified the /etc/samba/smb.conf file as detailed in the man page for
cupsaddsmb tool (had to add 'guest account' and 'map to guest'
lines to
allow PCs to browse the new CUPS server Samba printer share window
without needing a password. Note: account 'nobody' must exist). Here is
my smb.conf file:

# Date: 2008-05-14
[global]
   workgroup = BEC
   server string = Printhost01
   load printers = yes
   printing = cups
   printcap name = cups
   printcap cache time = 750
   cups options = raw
   security = user
   username map = /etc/samba/smbusers
   netbios aliases = printers
   netbios name = printhost01
   encrypt passwords = yes
   passdb backend = smbpasswd
#  wins server = 10.240.5.7 10.240.6.7
## wins server = 10.240.6.7
   wins support = no
   domain master = no

   guest account = nobody
   map to guest = Bad User

[printers]
   comment = All Printers
   path = /var/tmp
   browseable = no
   public = yes
   guest ok = yes
   printable = yes
   writable = yes

[print$]
   comment = Printer Drivers
   path = /etc/samba/drivers
   browseable = yes
   guest ok = no
   read only = yes
   write list = root


7) From my PC went to the new CUPS web page. In the Administration tab,
after logging in, added a Xerox Phaser 8560 printer as 'r4secrxerox8560'
- browsed to the PPD file which came on the printer's CD (Note: this PPD
file and the PostScript drivers files on the CD were used to
successfully set up this printer on our old CUPS print server).


8) Issued the following command to restart the samba process:

    /etc/init.d/samba reload


9) After the 'r4secrxerox8560' printer appeared in the new CUPS print
server's share window, ran the cupsaddsmb tool which completed
successfully. Here is the output from the cupsaddsmb tool for the Xerox
Phaser 8560 printer:
