Need help using my air printer and iphone 5s...it prints but the page is SMALL.

When using my air printer with my iphone 5s the pdf comes out very small. I've tried numerous times to print different pdf files (from attachments in email) and it won't print an 8 x 11 page, only 3 x 5 size. I finally tried again by opening it with adobe and it printed correctly. Is there a way to get it to work without using adobe?
