I bought the HP LaserJet M1217nfw a few months ago because it had the AirPrint functionality, along with laser printing and networked scanning, but until a couple weeks ago I had never tried printing anything significant on the printer from either my iPhone or iPad.
AirPrint is Apple’s wonderful wireless print-from-your-device feature! While studying for my most recent Salesforce certification exam, I wanted to print a 72 page PDF study guide. I was curious how the printer and iPhone would handle a document of this size, and of course with Apple-style ease it handled it without problem! (Sans minus running out of paper.)
I opened the PDF from Safari in Adobe Reader, one of many PDF apps for iOS that will print to an AirPrint compatible printer, and tapped on the menu inside the app to get the following prompt:
Simply tap on print and you get the following print dialogue which allows you to select the printer, page range, and number of copies.
The truly amazing part is that even when the printer ran out of paper, the iPhone had no problems - up popped an alert box, even if not in the app you printed from, and lets you know to correct the problem.
An AirPrint Printer is definitely worth the few extra dollars!
