Wireless Access, Multiple VLAN's

I have a client that has a "business incubator", consisting of a 1 office complex with 8 separate businesses within that office complex.  We would like to segregate each individual office onto their own subnet, but still be able to share one business class multi function printer.  This client will be sharing one internet connection across all networks, and would like to separate network traffic between different businesses, so that business "a" cannot talk to business "b".  This customer will also require wifi access for these individual businesses, so we are thinking of utilizing a layer 3 switch and just creating multiple vlans to accomplish this, but was looking for a second opinion on other solutions.

VLANs would be the best approach. I would create 9 of them though: one for each business, and one for any resources that are shared across all businesses. You don't have to get a L3 switch, but you do at least need either a managed switch or a smart switch (lower cost option).

Your title references wireless, which I see no mention of. Did you want to have each business be responsible for their wireless or are you providing those? VLAN capable wireless access points would be helpful as well.

How do you plan to handle authentication for the wireless? If you use RADIUS you may be able to assign the VLAN from the RADIUS server, depending upon which credentials are entered. Otherwise use multiple SSID.

You certainly need L3 switch. Put in access list on each VLAN so it can only access the printer (on its own VLAN) and the internet.

Yes you need an L3 device, you could use the router and have only layer2 switches, but layer3 switches will probably be faster, stackable, and reduce load on your router/FW
