Network: Can't reach specific device (printer) from fresh arch install

I have an old laptop with a working arch installation and my wifi HP printer (OfficeJet) is working there. As I got a new laptop, I installed arch fresh, made a list of installed packages on the old one and installed them on the new one. Copied config files and stuff (nothing from /etc), almost everything is working on the new one now. When I tried to setup my printer, it wasn't working with the script I wrote for the old laptop and I started troubleshooting.Now I reached a point where I found out that I am not able to even ping the printer from the new laptop, but from the old and all other devices I can ping the printer.

I am using Pi-hole in my network with dnsmasq as DNS / DHCP Server and this works on all other devices. All the devices have static dhcp leases configured in pi-hole and dynamic on the devices itself.

What I checked so far:

- checked /etc/hosts -> is identical
- checked /etc/nsswitch.conf -> is identical
- checked /etc/resolv.conf -> is identical
- checked /etc/systemd/resolved.conf -> is identical
- pinged other devices -> working
- arp -a -> is identical
- route -n -> is identical
- /etc/hosts -> is identical

I masked the hostnames and IP addresses below. LAPTOP2 is the new one, HPF65422 is the printer.

IPv6 ping:

ping -6 HPF65422
PING HPF65422(HPF65422.rob (CORRECTIPV6ADDR)) 56 data bytes
From LAPTOP2 (CORRECTIPV6ADDR) icmp_seq=1 Destination unreachable: Address unreachable
From LAPTOP2 (CORRECTIPV6ADDR) icmp_seq=2 Destination unreachable: Address unreachable
From LAPTOP2 (CORRECTIPV6ADDR) icmp_seq=3 Destination unreachable: Address unreachable
--- HPF65422 ping statistics --- 6 packets transmitted, 0 received, +3 errors, 100% packet loss, time 5061ms

IPv4 ping:

ping -4 -c 3 HPF65422
PING HPF65422.rob (192.168.178.193) 56(84) bytes of data.

--- HPF65422.rob ping statistics ---

Tracepath (not leaving the maschine):

arp (correct route):

arp -a

route:

What am I missing?

What really bothers me is that I just can't reach my printer from this maschine but from any other.
