Range of sizes
Receipt rolls come in different sizes, so it’s important you check the printer what size is accepted.
Freestanding till printers usually require a different size from card machines.
Till rolls are measured by:
- Width: Width of paper sheet.
- Diameter: Central, longest measurement across the circular side.
- Core roll diameter: Diameter of the internal roll.
The width is the most important measurement – if it’s too big, it won’t fit in the machine. Card machines tend to require a till roll width of 57 mm or 58 mm whereas freestanding receipt printers tend to need a 80 mm width. Widths can go down to 37 mm, while the maximum tends to be 80 mm.
It’s best to know the maximum diameter your printer can take, as otherwise you might get a roll that’s too fat to fit into the machine. That said, you can unroll and discard paper until it’s slim enough to go in.
The core diameter is the internal cardboard or plastic roll that the receipt paper is wrapped around. It rarely matters what size this is, as most modern receipt printers do not have a spindle going through the roll. Instead, you just dump the till roll into the receipt roll compartment turning the right side up.
Nowadays, you can get till rolls with no core roll. This is more environmentally friendly, as there’s no waste after the rolled-up receipt paper is used up.
