When you make your own decision to purchase thermal rolls,the first thing you must do is confirming the paper roll size. Here is a guide for fresher to teach you how to define POS roll size:
There are 3 parameter you need to confirm :
Width: that’s the paper roll width, it is usually up to your cash register width. For example, Epson usually use 80mm width,while credit card terminals use 57mm. Check our your machine or consult with the machine after-sale service staff, they will tell you the appropriate size fit for your machine.
Diameter: It is usually up to the machine hole depth. For Epson machine,it is usually 80mm deep,while for credit card/ NETS terminals, it is usually 40mm or 50mm deep.

For example,for 80mm x 76mm x 13.5mm, it means the width is 80mm, the diameter is 76mm, the core is 13.5mm. Take another example, for 57mm x 50mmm x 16mm, the width is 57mm, the diameter is 50mm, the core is 16mm.
