[Solved]Driverless Printing-New Printer just stopped working

[OldTango]

Set up a new HP OfficeJet Pro 8139e using Driverless-Printing. It worked until a few days ago where for some unknown reason it can no longer be seen on the network. It was assigned a fixed IP on a wired network via dnsmasq.

Code: Select all

#HP 8139e Printer
dhcp-host=24:6a:0e:4a:c9:11,192.168.0.130

Also through the Printers Web Interface.

Nmap shows the host is down.

Code: Select all

nmap -v -Pn 192.168.0.130
Host discovery disabled (-Pn). All addresses will be marked 'up' and scan times may be slower.

Have done all the hardware checks to confirm all switches and cables are in good working order.

The lights on the Printer's NIC indicate a solid connection to the network and appears to be receiving data. I can print the network configuration Report from the printer's touch screen. The report shows it to be properly configured, but is also showing a "Gateway Reachable Error" and refers me to Gateway Settings. The Gateway Settings for the Printer are correct: "Default Gateway=192.168.0.1" So either a Firmware Update (Firmware Version=6.23.3.71-202502131608) hosed the printer or a cups Update is causing a problem I can't seem to find.

What about hard power cycle of the printer ?

Thanks, should have mentioned it in my first post. I have already tried a hard reset as well as resetting the printer to factory defaults.

The lights on the Printer's NIC indicate a solid connection to the network and appears to be receiving data.

and nmap thinks the host is down

How does it receive the data then ? If you do a manual ping to the address, do you get a reply ?
What serves as a gateway ? Can you ping directly from a gateway ? ( If it is some router, it usually allows to ping from there)

I would start to think that the network card on a printer is busted

My Server is a Gentoo Linux based PC.
It is the Router/Firewall/Print Server/Rsync Portage Repository for all PC's on my LAN and performs several other functions as well.

I was relaying as much information as possible to avoid chasing my own tail and wasting other's time as well. I did ping the Printer by HOST name as well as it's IP address, from both Nmap and the command line just to be complete in my testing. I knew the ping test would fail even before I ran it.

While it's possible the NIC is broken, the activity lights on the NIC would lead me to believe otherwise.

Based on the Firmware Version installed (Firmware Version=6.23.3.71-202502131608) which looks to be a very recent update and coincides with the time frame the printer quit working on the LAN.

Without going into the several hours of work a tech buddy and I preformed. I do have the printer working on the LAN (via a WiFi connection) although that's far from an ideal situation. I can only get to it function via WiFi or a usb port attached to a windows PC.

I'm 99% positive a firmware update is what caused the issue in the first place. Several internet searches gave results of HP's firmware updates bricking printers very recently. Even more of HP's insanity, you can't revert to an older version of the firmware in the event an update fails. I tried to reinstall the firmware that shipped with the Printer, that I new worked but the printer refused to allow the install.

I always turn off automatic updates on my devices, this was the one time I forgot and it bit me.

Thanks Tango

You are probably right. I've seen several HP printers over my life with busted NIC's - would not be surprised by firmware updates . My own home HP WIFI locks like once a week, stops getting any data (of course I learn it each time when my wife needs to print urgently)- but reboot cures it.

In old days you could replace HP Nic fairly cheaply, not sure about now.

Same problem her. HP OfficeJet Pro 8132e recently firmware upgraded to 6.23.3.71-202502131608. I can't enable DHCP or manual setting of the ethernet interface so it isn't usable. But if I disconnect ethernet, WiFi works.
