To ensure that you get the print that you want, you would probably want to use the 4 x 5 (8 x 10) crop ratio when cropping the image.

You will set Paper size in the Page Setup of the Printer dialog. (Depends on what printer you are using)

You will set margins and photo cell size in the panels of the Print module.

Do not use the provided default page templates (they are all 'Letter' size).  Save you own template when you have set the options for your requirement.
