The outside packaging causes the paper to buckle. The buckled paper does not feed through the printer. I purchased enough packages to total 300 cards. I waisted 1/2 of the cards pulling them out of the back of the printer. If I had enough time I would have return all the packages and used something else. But since I was printing at midnight I was out of luck and had to use what cards did going through the print nicely. NOT A HAPPY CUSTOMER!
