Does this work with HP Sprocket printers?
Did this have expiration dates?
Yes. But hopefully you still have a blue card from the HP paper. You’ll need to use that with the Polaroid paper to tell the printer that you have the “correct” paper.
From the website
“The only thing you need to do in order for it to work is use the blue Zink Smartsheet card for the HP Sprocket with the photo paper from the Polaroid Zip. The blue little card is what lets the printer know that you have the right paper, so just swap out the Polaroid card with the HP card when you load in new paper, and it’ll work perfectly. Make sure you keep the blue card and just reuse it each time.”
