Isolating Network Traffic

I believe I have a computer on my network that is trying to send print jobs to one of my printers. Every time I put the printer back on the network, it prints garbage. The printer interface, HP m401n, does not tell me the computer/IP sending the job. Is there something I can install on my machine that can search for network traffic to the printer's IP?

i guess you must have known the printer's IP address and host name, right?

if the answer is YES and all computers and printers are sitting on the SAME subnet (in the same broadcat domain), you may just install Microsoft Network Monitor on a computer to monitor any BROADCAST traffic looking for the printer by host name or IP address.

if a computer intends to access the printer and already know the printer's IP (by quering the DNS or WINS) it must first send a broadcast to ask which host is on the IP. the broadcast packet can be seen by all hosts on the same network, hence can be captured by your Network Monitor.

BTW, you no longer need the printer staying online for catching the computer.
