Paper works PERFECT in the Jaden thermal printer, the one that prints letter size. Just remember, the roll has to have the paper pulling out going OVER ...not "UNDER". Think of a toilet paper roll. The paper pulls off on the TOP, not from UNDER. I noticed a friend who also got the Jaden thermal printer had their thermal paper inside of the little printer pulling out in the wrong way. They flipped over the roll and inserted it the correct way. It printed out perfectly. Hopefully this paper is PBA free like stated but who has the means to test it? Thankfully, these are often used in schools. We can take it to one of the labs for someone in their to test it.
