How do you print photograps on my MG5520 wirelessly from my computer (Lenovo Yoga).  When I push print no picture is printed, the paper just comes out blank.  Thank you!

I have the original EOS DSLR that came out in 2004.  It's working ok, just slowing down.  I want to buy a new Canon and was wondering if the original lens, the 18 to 55, would fit a newer camera.  I also have a Tamron zoom lens I got back in 2006 or ...

How do I copy a 4x3 photo onto and to fit 5x7 photo paper?  Do I have to scan it first into Picasa to enlarge it or can I do that directly from the computer?
