HPLIP can't detect printers on my network

Asked by Ken Wright on 2019-09-23

I have an HP LaserJet Pro P1102w the computers in my house access via WiFi. At least, we try to. Sometimes it works, then after a reboot it doesn't. I checked the troubleshooting section on the website and opened ports 161, 162, and 9100 for both TCP and UDP but I still can't detect any WiFi printers, nor can I ping the printer. Any ideas or suggestions are greatly appreciated!

Hi Ken,

In order to detect via Wi-Fi, printer and your system should be in same network. After reboot, please check if your printer is connected to the same Wi-Fi. You do not need to open any ports to connect through Wi-Fi.

Hi Shivani!

I've checked, and the printer is on the same network. I printed a configuration page, and it shows the correct SSID, the correct IP address, subnet mask, and gateway. But looking at the network information, I see the network status is "Not Connected". I think I've found the problem, now to find a solution!

Further info: I am now able to print from my wife's MacBook wirelessly. Sounds like a step forward to me!

Latest report: I can print from my laptop wirelessly, but HPLIP still can't detect the printer (Ubuntu's printer utility was able to install the printer with a Foomatic driver). I can remote into the printer to change the settings, so I'm dead sure it's the same network and it's visible to everything except HPLIP. Does this make any sense to anyone?
