I've had trouble with Carol Doak's running through my HP LaserJet 6P. The only way I can get it to work is to feed it through the single sheet tray one piece at a time. Otherwise, it pulls three or four sheets, and not at the same time. I end up with the design only partially printed on several sheets. It's not difficult to feed them through one at a time. Still, I wish it would work the way it's supposed to.
