I am trying to print business cards and have bought pre-made sheets to print them out on. They are "Avery". It holds 10 cards per sheet, and it's 2"x 3 1/2". On the box it says I should use a template called '8371", however I can't find how to get to it anywhere. When I've tried to print them before, I've found space between the cards, when there is none in the sheets. Help, please?
