[SOLVED]Resolving xxxxxx.local doesn't work

I have added a network printer to CUPS using DNS-SD/mDNS and everything seems to have gone fine, but when I try to print something, the job never gets to the printer and it ends up showing the error: Could not locate printer "NPI099206.local".

❯ host NPI099206

I use NetworkManager with dnsmasq to resolve DNS.
I have searched for solutions on the Internet but none of them work for me.

Re: [SOLVED]Resolving xxxxxx.local doesn't work

Sorry if I'm missing something here, but your output is clear: the name is NPI099206, not NPI099206.local, so it's not surprising that the latter could not be printed to.  You either need to configure printing to the name without .local, or change the naming to include .local.

This is the CUPS printer, the dnssd connection doesn't work. The address detected by CUPS is provided by Avahi.

❯ avahi-browse --all --ignore-local --resolve --terminate
....

   hostname = [NPI099206.local]
....

Avahi reports the printer hostname is NPI099206.local. But it is unreachable from my computer.

hosts: mymachines mdns4_minimal [NOTFOUND=return] dns mdns4 resolve [!UNAVAIL=return] files myhostname

That configuration is nonsense.
https://wiki.archlinux.org/title/Avahi# … om_working but there's no systemd-resolved…?

nameserver 127.0.0.1

What is your local DNS server? dnsmasq? stubby?

pacman -Qs nss-mdns
systemctl status avahi-daemon.service

Re: [SOLVED]Resolving xxxxxx.local doesn't work

I have tried different configurations because there is no consensus on which one is correct. https://wiki.archlinux.org/title/Avahi# … om_working https://github.com/lathiat/nss-mdns/blo … activation and so on... It's very frustrating.
None resolves the printer domain to .local.

I use NetworkManager with dnsmasq.
I do not have nss-mdns installed.
