We current have a print server that handles a lot of printers, about 350. Cups is handling printing on the SLED 10.1 system. When Lotus Notes client 8.0.2 starts up or tries to print, hundreds of ipp connections are initiated to the print server. The process, either startup or printing, hangs until most of these connections time out.
There are no problems printing from any other application that I have found, including OpenOffice, Firefox, and command line.

I’m not a print or Linux expert, but I know of no reason why the notes client would initiate connections like that on startup. Is it when the client starts, or when a particular application is opened? Perhaps the application attempts to automatically print something(s) in the DatabaseOpen event? Does this happen on all clients, or just one? I would look at the client log, perhaps enabling higher logging, to see exactly when/what is happening. If that doesn’t tell you anything, you should contact support.

While starting Lotus Notes 8.0.2 for Linux, I also captured the network traffic using tcpdump. During the startup there were over 1.5 million ipp packets between the local computer and the print server. I tried turning off cups, but this had no effect on the amount of ipp packets. Does Lotus Notes communicate with print servers on its own and bypass the native printing system?
