I have a HP Photosmart inkjet. I have used both kinds of paper in my printer. Maybe you could try one sheet of either of your kind and one sheet of regular copy paper. Your printer should be able to handle what you are doing. Sometimes The printer needs a piece inbetween especially if it is very thin and a in between if it is very heavy why I don't know :roll: . If this doesn't help you should contact HP they have a web site and ask them what to do. Good LUCK
