@donz: yes you are right. I could print but still got the "access denied" message. With the "use client parameter = yes" the system says that the printer is operational.

I am getting the following error upon SMB restart:

Starting SMB services: execvp: No such file or directory [FAILED]

That doesnt look good!!!

I have set the configuration that you suggested. Going to see if that has made any difference

is it use "use client parameter = yes" or "use client driver = yes" and where does it go? I have tried "use client driver = yes" and the print queue gets stuck "Initializing"

Cool this works, the print queue takes an age to initialize though!

I also have a print job that seems to be stuck there... it says it has "Printed" in the status bar. How do I delete it? I cant do it from windows...

if you can´t delete it from windows, change on your unix printerserver to the lpd directory and delete the file you find there you may need root to do this. If you want to do it more comfortable you can do this from your windows client over the ssh service of your Linux box. If a ssh deamon is running, get the ssh and telnet client for windows. its called putty and works fine. with this tool you can logon to your linux box and work using the console.

I use putty all the time... thanks for your help!

You can also use the lprm command.
For example, to remove all jobs in spool queue p1:
lprm -Pp1 all

More is available in the lprm MAN page.

Ok, thanks for all you help
