This post is a little old but I thought I would throw my 2 cents in here.
It sounds like you have an internet connection connected to a router that has Wired and Wireless capabilities. The printer is wired in and you just print from the PCs right now.
Has the wireless functionality of your router been turned off? There is no reason it shouldn't be able to operate at the same time. That's sort of the whole point.
iPhones should be able to connect to the wifi at the same time.
The only thing I am not sure of is how you can print from your iphone. I've never heard of this functionality before. And I have an Android so I can't test.

Yeah that kind of sucks. Your basically looking at a factory reset and you'll have to set everything back up.
Your safest bet, since your wife cannot lose VPN connectivity for work purposes, is to buy a new wireless router to play with until you get it all setup correctly. That way you can have the old one plugged in while she works, and the new one to play with when she is done for the day.
