CAn I go directly from a iPad ,iPhone to a AirPrint capable printer?
No. You need to have your device connected to the same network that the printer is connected
SInce I do not have a Internet service at home, can I connect a wireless router to my Mac and set up a wi fi network as" stand alone?
You can, but it's a bit useless if you haven't got an Internet access (of course, you can use it for AirPrint)
LEt me try again. I have a Mac (1 year old) iPad -1, and a iPhone 4 (that I use to connect to the Internet) and a 5 year old printer. How can I print from my phone or iPad either wired or wireless.
Your printer is too old to support AirPrint. It requires a printer with Wi-Fi
WHat do I need to buy in addition to a AirPrint printer?
If you have a wireless router, nothing more. Just connect the printer to the router
Another approach would be to use Printopia on your Mac to drive your existing printer and provide a Airprint compatible virtual printer to your network. You will still need the Wifi router, but not a new Airprint compatible printer.
