A:AnswerNot sure why you would want to enlarge a tiny print later? Why not just print larger first. You can make larger prints at places like cvs, Wal-Mart or walgreens for low cost.
I'm sure you can enlarge this tiny print but i would imagine the quality would be horrible.
A:AnswerThe only difference I can tell you is the HP Sprocket works. The poloriod zip would not work on my phone. I even replaced my phone but it still wouldn't work. I had absolutely no problems with the HP Sprocket. It even fits in the case I purchased for the poloriod zip.
A:AnswerNever bought the HP but in my decision to but which one I was leaning to Polaroid because they have been doing this for 50+ years. I figure they have it down by now.
