The solution was to change printer setting:

That implies the problem is your router or printer - nothing to do with
gentoo.
Using the IP address is dangerous - unless you've explicitly configured
stuff, it can change ... At the end of the day, everything here is a
pain in the arse if you are using DHCP, and if you're using static IPs
it's a pain in the arse too ... :-)
What you want to do is configure your printer to send its DHCP with an
"I am called X" message. Your DHCP server (I guess it's your router)
then needs to configure DNS so that X matches whatever IP address it
hands out (that *should* happen automatically). Then everything "just
works (TM)".
The trouble is it sometimes doesn't "just work". With my router, I know
I have a local range of 192.168.1/8. And it's configured so that 1..127
are available for random DHCP allocation. 128..254 are static addresses.
and 0 and 255 are broadcast and router respectively. That's of course
all if IIRC.
But then, for my server(workstation) and printers I've then allocated a
static mac->IP mapping, so I can put a hard-coded entry in my hosts
file. Stuff I don't care about, laptops, mobile phones, games boxes, etc
just get a random IP.
Basically, you need to understand how DNS, DHCP, and all this name
allocation stuff works, and it's pretty logical. It just takes quite a
bit getting your head round it.
