Photo Resizing

I want to print out pictures at different sizes - larger or smaller pictures than what prints out of Photos app as the "default" size of the printed picture.

How do I do control enlarging or making smaller the size of the printed picture that comes out of the printer?

I am using Photos app for Mac Version 2.0 (3161.4.140)

If it's relevant, my printer is the HP OfficeJet Pro 8710
