We're talking about the ultimate VFM. The only thing that makes me curious is how when a receipt is issued, the ink color isn't intense, but when I cut Z, it's just fine.

However, it's probably a matter of POS and not the thermal paper.

It's not 57x40 but 57x34, so you receive a smaller quantity than what you are supposed to be getting. Otherwise, it does its job without any issues.

The films are said to be 40mm in diameter but they don't even reach 35mm. Other than that, it's a simple thin paper that will do the job it's intended for.
