Sheree.
I don't know if you ever resolved the problem with the fabric photo paper. I have an HP too and have not had any success using any of the commercial paper. It seems it's too thick because it jams. I have had success with paper backed fabric I've made myself but the fabric is not as good quality as the commercial one. What I do is use freezer paper and I iron my fabric onto it, then I cut it in 8 1/2 x 11 pieces. I have no trouble feeding this into the printer. Let me know if you've found a way to resolve this.

I have to agree with Anna. Applying freezer paper to the back of your fabric is a great suggestion. I read this in a book. I wish I could take credit for it. One other suggestion that no one else mentioned: Don't do on a humid day! Humidity does HP printers no good.

Wishing you luck,
