My daily driver printer is an HP 401dn, probably 10 years old by now that gets only light usage in a home office with two users. Recently it spontaneously goes offline. Power cycling the printer sometimes restores the printer to online status. Sometimes if there is a document already in the print queue, it prints a minute or two after the printer has been cycled.

Does anyone know what board or part needs to be replaced? Is this something I can do myself if I have the skill-sets to build all my desktops, etc.

How do you have the printer connected. Can you use another interface, USB or ethernet?

The printer might go into standby and cannot wake. I would try first to disable standby (make it always on). If that's not enough, next step is to connect it to one computer via USB and share it so the others can print.

That is due to it losing the assigned IP address.
That used to happen to my old HP printer occasionally.

Look in your Router and find what IP address has been assigned be it manual or by DHCP.

Use the HP App and change the address of the Printer to match.

Power cycling/reset printer may change that as well, sometimes. It is better to analyse the problem and reliably fix it.

I have to say my new Canon printer is much better and does not do that, it has been network connected for 5 years.

My old Canon from... 2009 Pixma MP990 only ever has an issue if I power cycle my router. Just power cycling the printer will put it back online. I have it connected by ethernet.

Setting a static IP in the printer is not a bad idea. It makes sure is always available even if the power cycles.

For my system that isn't the problem. It always has the same IP. It is that if it loses connection when at idle, for example if I reboot the router, the printer does not have any mechanism to auto detect this and reconnect.

So back to what I suggested in my previous post. Configure the printer to always stay on, never go standby.
