I thought I sent this already but here is another copy of Wireshark output after I submitted a print job. My printer IP is 192.168.50.98 and the computer is 192.168.50.104. Gary
1. I assume you are not using a print server in your setup?
2. I assume you are not using any type of accounting or authentication settings on the printer?
3. If the printer has a completed job log, see if the jobs you are printing are actually getting to the printer job queue, but then being deleted for some reason (without providing a message)..
