I too have a HP photosmart. Don't use it for copying pics tho. I found out that u can't enlarge on this 1. The one I had before could, sooo next time I'll be more diligent as to the functions. Have found out, thru trial & error, that if u enlarge on the 'view' of the document 1 or 2 times, the test square will be 1 inch.
