Hello there. Weird thing: Last year, I had Leap 16 installed and added the HP printer with hplip (through Network/Manual discovery … ) all good; it worked.
I did a total new install (don’t ask why) and now I cannot add the printer anymore.
There is an error message about firewall settings :
HPLIP cannot detect printers in your network.
**This may be due to existing firewall settings blocking the required ports. When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall.

Okay, strange but whatever. I added the ports and my firewall looks like:
henry@LaptopXPS:~> sudo firewall-cmd --list-all
public (default, active)
target: default
ingress-priority: 0
egress-priority: 0
icmp-block-inversion: no
interfaces: wlp0s20f3
sources:
services: dhcpv6-client ssh
ports: 5353/udp 427/tcp
protocols:
forward: yes
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
Done. New try. Nothing. Same error message. Any good advice?
(But how strange is it, that everything was fine the first time but no more today?
Appreciate all help
