[SOLVED]Cups hangs up after printing

I have a HP LaserJet1606dn printer. Connected to my desktop machine, then tried to share over the house network. While this is done, through the other machines I created some more instances of the printer, so I deleted the all, and through the CUPS web interface recreated one. Now I have two instance in every applications prinitng panel, but CUPS shows just one. When I do a print job, right after it is started, CUPS gives up communicating, and I have to restart the service. Is it better idea to start it as a socket, or is there a way to solve the problem?
TNX!

$ lpstat -s

Where's the F2400 coming from?
And then there's obviously the residual Hewlett-Packard-HP-LaserJet-Professional-P1606dn-?.strings files.

Edit: about the hangs, see https://wiki.archlinux.org/title/CUPS/Troubleshooting
Raise the log level to debug and check the log when the cups daemon hangs.

Re: [SOLVED]Cups hangs up after printing

F2400...
Hm. Maybe an old printer from the neolithicum... We had one, but it' went dead, and I removed CUPS fully (I thought). For years I had nothing to print out to this year.
I will check it.

Re: [SOLVED]Cups hangs up after printing

HM. I found, that the printer goes "dead" state as cups describe it, but after a while (looks like depending on printed quantity) the printer gets back to "idle" state. Maybe cache emptying or something happens in thi stime.
