|guest network should be segmented from the business network.|
It should have its own printer.
most small offices don't provide guest internet access or if they do its a completely different network than the business network.
at least those that know better. I have seen guest networks tied to business networks.
Another way of accomplishing this is with two routers. Guest router is the main router. Business router is off the guest router. Both get internet but guest can't access business.
Best way to accomplish this is to use a vlan switch off the main router.
You set the internet connected port going to the router for both business and guess network. Guest network router off the switch gives dhcp/internet to all guests. Guest vlan has no contact with business network.
Note that the main router is not a wifi router just a plain router. If you do wifi to business then you defeated the purpose. If you want wifi for business then you need three routers; main, business router and guest router.
You would still need to put a printer on the guest network as well as provide them with the printer install.
