Re: AirPrint vs. Series driver...
I've seen this a lot. If you're finding the printer (presumably network, maybe wireless), when you go to add the printer, you'll get a few choices. Unfortunately, the "...Series..." printers sometimes take a bit longer to show up. So you have to wait until they appear. Once those appear, then chose one of them & you will find it using the correct (well, of the choices) one rather than the AirPrint.
