printer for guest wifi

I want to add a printer so that guests on our guest wifi can print to it. I put it on the guest wifi. But then it turned out the computers and iphones also on guest wifi could not see it. It turns out this is a feature. Then I went to the router (netgear genie), and there's an option "Allow guests to see each other and access my local network", which was off and is off by default. I do not really want to turn that on, since I do not want guests to be able to get to the computers and printers on my regular non-guest wifi. I don't mind if they see each other. Any suggestions? Thank you
