I have an Epson 9600 wide format printer, we're experiencing issues where the print job fails, always at the end.
I've noticed that every time the job fails, the PC is sending standard ACK packets
Output from a successful job: https://www.cloudshark.org/captures/47c1282d852d
Output from a failed job: https://www.cloudshark.org/captures/d54ab50636c1
I'm stumped, to be perfectly honest I'm shooting in the dark. Tried LPR vs RAW printing, tried different machines etc, still failing. Any help would be greatly appreciated!
edit: bit of extra info, printing from a mac works fine every time. o.O different TCP/IP versions/settings/something?

A lot of important information is defined at the session start, which we can´t see here. So maybe we need it some day. The main difference between the traces as we can see is the termination of the session. In the successfull trace we can the a normal 4 way session closing (FIN-ACK)
In the failure trace we see an anormal session termination indicated by the RST-Bit. In the most cases I analyzed was the root cause a problem above Layer 4.
Maybe it is a driver problem at the 192.168.1.91 because this machine sends the RST apparently more or less unmotivated.
