What's the deal with the thermal paper though? I guess it's negligible exposure since you would only be using it once a day. There is an alternative thermal paper that uses vitamin c. It's slightly more expensive but I feel like that wouldn't matter for something like this since it's not using nearly as much as would be used for retail printing. I wonder if it's worth using the vitamin c kind instead.
