Got some Hammermill linen business card stock on eBay. Standard 8.5" x 11" sheets. Good price. Using our HP Officejet 5610 printer... the cards will not print properly and line up. The cards are formatted in MS-Word and they line up perfectly on the templates supplied by Hammermill. However, are putting in the linen card stock - the business cards print out differently each time. They never line up properly as the way they seem to on normal paper, i.e., the template. What in the world is going on? Has anyone done this before? Why would the way these cards are lining up in MS-Word be different when using the business card stock? Is it a hardware issue with the printer... or a software issue with MS-Word? Help or suggestions?
