Hi,
you can also do a port scan for the IP address of the printer connected to your Wifi network. In my case the following ports are active.
For scanning PeasyScan also doesn't detect my HP, but I can scan by providing the IP address in a config file. Printing and scanning are working on different ports.

Port 631 is used for Internet Printing Protocol. I assume this is what CUPS in my case uses to communicate and print.xxx.xxx.xxx.xxx : 80
xxx.xxx.xxx.xxx : 81
xxx.xxx.xxx.xxx : 82
xxx.xxx.xxx.xxx : 83
xxx.xxx.xxx.xxx : 443
xxx.xxx.xxx.xxx : 515
xxx.xxx.xxx.xxx : 631
