#599 Cannot connect to canon MP620

[conrad]

Hello. I'm on High Sierra 10.13.6 and I'm trying to install a canon mp620 over wifi at home. I'm using the correct IP address as I can reach the pinter homepage. When I try to install there is a warning message that tell me that the printer cannot be verified on the network due to an error. I can create the printer but then It won't connect anyway. Tx for your help
