Continuous stationery (UK) or continuous form paper (USA) is paper which is designed for use with dot-matrix and line printers with appropriate paper-feed mechanisms. Other names for continuous stationery include fan-fold paper, sprocket feed paper, burst paper, tractor-feed paper, and pin feed paper. It can be single-ply (usually woodfree uncoated paper) or multi-ply (either with carbon paper between the paper layers, or multiple layers of carbonless copy paper), often described as multipart stationery or forms.
