Comment 65 for bug 283811

I had the same issues from my Ubuntu (Jaunty) client.
Situation might be a little different from others.
In my case, inkjet printer is physically connected to the other Ubuntu server (Hardy).
I have printed through samba share, but it hasn't worked since the OS of the client was updated from Intrepid to Jaunty.

My solution is publishing shared printers on the server side.
To do this, go to System > Administration > Printing > Server on the server side.
Check "Publish shared printers ..."
Check "Allow printing from the Internet"
Then, on the client side, I removed all printers that were manually set up,
and checked "Show printers shared by other systems" at System > Administration > Printing > Server
Then the client detects the shared inkjet printer, and a new printer icon soon
appears on Printer configuration window on the client side.
It was successful to print a PDF file and test page through
the automatically detected shared printer, and printing is working fine so far.

Hope this helps.
