Normally,
for printing,scanning over wifi you need the ip-adress of the printer.
You can either look on the printer setup-display to find it out, or you look into your router/dhcp settings,
or if both will not work you could install arp-scan
and search the ip with
sudo arp-scan --localnet
If you found the printer’s ip-address open control-centre -> Hardware -> Printer Settings
Click on Add
Next screen has a Network Printer dropdown. Click on it. If you see your printer there already do NOT select it.
Instead select Find Network Printer. Enter the ip address of the printer there and click on Find.
This should work.
