A roll of paper is a cylindrical object that contains a continuous length of paper. It can be used for a variety of purposes, such as printing, drawing, or writing. The term 'roll of paper' can also refer to three different objects: a SCROLL, a WEB, and a BOLT. A SCROLL is a long, rolled-up piece of parchment or paper that is used for writing or drawing. A WEB is a continuous length of paper that is wound onto a spool or reel. Finally, a BOLT is a large roll of fabric or paper that is usually sold in a single length.
