Why are Askpi rolls slightly narrower?

All Askpi Systems thermal paper rolls are manufactured approximately 1–2mm narrower and/or shorter than the industry standard specification. This small tolerance is intentional — it ensures the paper feeds smoothly through the print head without catching on the edges or jamming inside the machine. Standard-spec paper can sometimes be too tight a fit due to manufacturing variation across different printer brands. Our rolls are compatible with all devices rated for the industry standard size.

Common Questions

Frequently Asked Questions
