Your Owner printer uses standard thermal receipt paper. The width matters, but the roll length doesn't.
Your printer uses 3-1/8" thermal paper.
The 3-1/8" width is required. Other widths may fit, but the text won't line up, and this can't be adjusted.
The 220' length is just how much paper is on the roll, so longer or shorter rolls are fine.
Your printer comes with a starter roll to get you going. After that, you supply your own paper. It's inexpensive and easy to find, and a typical pack costs around $20 from retailers like Amazon.
Load the roll so it feeds from the bottom of the printer.
ℹ️ Note: Thermal printers only work with thermal paper. Regular paper won't print.
