HP OfficeJet Pro 7740 firmware bug causes fault when connected to company LAN

[SethHB]

Printer firmware crashes and enters a fault state after being connected by either wired or wireless connections to the company LAN.

Received a replacement printer that exhibits the same behavior straight out of the box. My money is on this being a firmware bug. Trying to explain this to the telephone tech support agents is an absolute lost cause. All they seem capable of doing is having you reset the printer a million times and then creating a ticket to have the entire printer replaced, which does not solve the problem.

Please let me know where this can be escalated for proper troubleshooting and identification of the bug so a fix can be pushed in the next firmware update.

I did some further troubleshooting by running a Wireshark capture to see what kind of network activity is taking place before the printer faults. I noticed traffic between my workstation and the printer took place shortly before the fault occurs.

To troubleshoot, I powered my workstation off, then restarted the printer. The printer now boots and stays running even while connected to the network. I setup another Wireshark trace on another computer, then booted my computer up. The instant that wireshark recorded a single ARP packet broadcast from the printer to my workstation, the printer entered the fault state.

Below is a screencap of the wireshark trace with the offending packet. All I did was boot up my Windows 10 workstation, I did not log in.
