@Rachel-Horne I have one of those printers. Are you using the automate function in photoshop for Canon's Print Studio Pro to do your printing?
A lot of the time I use the PRO mode and if it's dark I'll go into the colour settings and bump the brightness to +30.
Also make sure you select the right paper setting in here. I had issues with brightness by selecting the wrong paper for ICC and so I loaded the right one from the paper makers website.

I'll always check the levels graph setting in photoshop as this gives me a good idea of how light or dark my image is.
Also buy some cheap thick a4 paper to print onto first or postcards to save on ink and mistakes.
