HPLIP cannot detect printers

[sbob]

All; I am running Fedora 38, and I have the following installed: 
hplip-common-3.23.5-8.fc38.x86_64 hplip-libs-3.23.5-8.fc38.x86_64 
hplip-3.23.5-8.fc38.x86_64 hplip-gui-3.23.5-8.fc38.x86_64

I am trying to setup a new HP Color LaserJet Pro MFP 4301fdw

when I run hp-setup and plug in the printer's IP address in the 'Manual 
Discovery' box I get this:

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. For 
detailed steps follow the link.
