Owners of Canon's PIXMA MG8220 and MG6220 Wireless Photo All-In-One (AIO) printers will see the upgrade, which requires a firmware update in order to take effect.
Google Cloud Print allows users to print from, well, the cloud. With the functionality, documents can be printed remotely from both mobile devices and desktops, the utility of which should be fairly clear. Users can also share their printers, making the whole process of set-up and installation significantly easier.
Both the MG8220 and MG6220 were announced last summer, so they aren't the newest of devices. Fortunately, in May Canon will add similar support for the PIXMA MX892 Wireless Office All-In-One. This printer was announced only a few weeks ago, and comes with out-of-box support for Apple Air Print. Clearly, cloud-based printing is quickly becoming a standard feature for Canon's printers.
