[Solved] CUPS no longer sees my network printers

[yankeeFarmer]

Hello everyone. I have a strange problem that I am unsure where to start with. I have a fairly new Bookworm install, and everything was working fine. I am not new to Debian, having switched in 2005, and I've dealt with a lot, but networking issues have always been my weakness. Anyway, I went to print a document, and had no printers anymore. I went to localhost:631, and nothing was listed as a network printer. Blank. I have an HP Laserjet 1109w, and an Epson ET 2850. All have worked in the past, and now neither is visible. My android phone can connect and print without a problem to either one.

Another thing that may or may not be related, but equally strange is that I can no longer access my openmediavault server at user@openmediavalut.local, but can access it with user@192.168.0.88. Swapping the quad address for the openmediavault.local restored the rsync funtionality. (I ssh into the server for backups).

Let me know whatever other information is needed, and thanks in advance!

Update: For some reason unkown to me, everything is back. I have no idea what is going on here.

How did you set up the printers?

Both printers are driverless enabled - they use Airprint - and a print queue would have been set up in Bookworm automatically, no driver required.

This is a fairly recent change. Please check the following page. Apologies if you are doing this already. It may be that you are fighting against the system if you are still using old approaches to setting up the printers.

It could have been a router issue with Bonjour, maybe?

Thank you for the info Frank. You may very well be right in that I am still using old methods on new systems. Old dogs, tricks, and all that, LOL I'll check out those links and maybe learn a few things. I still wish I knew why they disappeared and reappeared. Obviously, something had changed, but I'll be darned if I know what it was....
