It's interesting, though, that some Members have still had problems even with supposedly 100% AirPrint compatible printers but those problems do seem few and far between. I have a non-compatible printer and use PrintCentral and the WePrint PC app, since my printer - a Samsung colour laser printer - is not directly compatible with PrintCentral. But, for sure, if you purchase a printer from this list (and be careful, because HP sell a number of printers that have the same model name but then have additional options to make them AirPrint compatible).
Let us know how you get on.
