It can be difficult to get the content you want printed from emails or photos on your iPad, iPhone, or iPod printed out to a hard copy. Generally, if you have a printer that lacks printing from mobile devices natively you need an email account you can forward to before you can print them up. Many new printers out there allow printing directly from mobile devices via an app so you don’t have to bother with email or other methods.
Canon has announced that several of its Pixma printer models now support Apple AirPrint for the iPad, iPhone, and iPod models. AirPrint support is now offered on the Pixma MG8220, MG6220, and MG5320 printers. That means you can print anything from photos to email, web pages and documents with no need to mess with drivers or apps.
AirPrint natively allows you to print that sort of document. You will need to update the firmware on the printers to support the new feature though. With the firmware installed, you will be ready to print your documents. The iOS devices need to be running iOS 4.2 or later to print.
