    Easy Peasy !!

    Well it really couldn't have been any easier. Order del'd next day as promised and wirelessly installed by simply following the on-screen instructions in just 40 mins. Print quality & speed excellent. Although print cartridges aren't the cheapeast I've yet to purchase an HP printer that doesn't do exactly what it says on the box. This purchase has reinforced my confidence in HP products.

What is AirPrint?

Apple AirPrint allows full colour, top-quality printing from iOS devices such as iPhones and iPads directly from within many Apps available from the Apple App Store.

To take advantage of AirPrint, your compatible printer must be connected to the same wireless network as your iOS device or Mac computer.

AirPrint enables users to print wirelessly from within applications on Apple devices to AirPrint Compatible Printers connected to a wireless network. You can use your iPhone, iPod Touch or iPad to easily print via Airprint without the need to install drivers or configure the printer queue. Just tap 'print' and select your AirPrint compatible printer, and print!....It's that simple.

What You See is What You Print

If you can open it on your apple device, chances are you can print it with AirPrint and an AirPrint compatible printer. Airprint works with Safari, Mail, Photos, iWork, PDF's in iBooks and many third-party AirPrint compatible apps available from the app store.

Full list of AirPrint compatible printers

Third-Party Apps

There are also a wide variety of third-party apps available to enable wireless printing through Apple devices, even to machines that are not natively AirPrint compatible printers. By sharing a printer installed on an Apple Mac or Windows Pc over a wireless network any printer may be able to take advantage of the AirPrint features. (An additional third-party app may be required to be installed on the local machine)

*For full AirPrint support, a printer firmware upgrade may be required which is available directly from the relevant manufacturer website.

Please note. Whilst every effort has been made to ensure that the above information is correct at the time of publication, Printerland will not be held responsible for the content of any third-party software suggested on this site and usage of any such software is at the users own risk. Printerland is unable to provide support for Airprint compatible printer software and any such advice should be readily available from the relevant manufacturer or developer.
