Two-ply carbonless paper is great for impact printing machines and point of sale (POS) systems. Once imaged, the paper instantly produces a duplicate copy. The imprint is clear on both copies. One ply is white, and the other is canary. End-of-roll indicator conveniently lets you know when it's almost time to replace the roll to prevent unexpected runout. Easy-to-install design allows simple roll replacement to save you valuable time when changing your depleted roll.
