I just set up a Phaser 6022 to print from my MacBook running Yosemite. Prints fine using USB, but the printer manual only provides info on configuring wi-fi for Windows. What do I need to do to print via wi-fi? Thanks.
You install the printer the same way as if it was on a wired network in either case, the method of the network doesn't matter.
So put the printer on the network and verify the Mac can see it by opening its web interface (Open safari and put the printers IP address in the address bar)
Once they can see each other install the driver to it via Apple > System Preferences > Print and Scan
It should be discovered by Bonjour/Appletalk, but if not just pick the IP tab and enter in the IP.
