Abstract: An improved reusable media carrier having positive alignment capability and improved carrying characteristics for advancing one or more pieces of printable card stock media or the like through a computer printer, word processing printer, or copy machine. Such means is in the form of a flexible rectangularly configured carrier, particularly suited for use with printers or copy machines having friction, sheet-feed mechanisms. The carrier is comprised of an essentially rectangular sheet of paper or other flexible material folded in such a way as to provide retainers for positively engaging at least two adjacent side edges of a piece of media to be printed. In addition, the retainer means may include hard stops for effecting positive media alignment and location. Furthermore, the carrier may include embedded strips of stiffener material for minimizing curl of the media carrier.
