A:AnswerYes. Canon Print Service app on Google play store app will allow you to print from your android phone. Check the settings before printing, I believe the default paper size will be 8.5x11 unless you tell it otherwise. Good luck!
A:AnswerIt supports 2 side printing, but you have to physically flip the stack over and set it back in the feed stack-odds, then evens. So the short answer is no, it doesn't print duplex by automatically flipping each sheet.
A:AnswerI find printing lots of sizes of prints and over many colors that I spend about $1.25/ square foot for ink alone. This is paying retail for the cartridge's. A 4"x6" print is 1/6 sq. foot so you might spend $0.21 for one 4x6" print.
A:AnswerElkaMae, this is not a “printer” issue, rather the capability to print multiple images on a single piece of paper has to be available in the software program you are using to print the pictures. Depending on the device you are printing from, e.g.Windows or Mac PC, iPhone or iPad, there are a number of different options available. Canon software provided with the printer may have that function as well. The 8720 will print anything the software sends to it.
