Abstract
Abstract An arrangement of lines of perforation on computer paper is disclosed. Horizontal lines of fine perforations are placed at intervals of 2.75 inches throughout the entire length of a single length of computer paper, and three vertical lines of fine perforations run the entire length of the paper, one each at a one-half inch distance from each edge of the paper, and the third line at 9.00 inches from the left edge of the paper. By virtue of such arrangement, a single length of computer paper can produce at least three standard sizes of page rather than only one size as in the prior art, obviating the need to change the paper each time that a different size page is desired. Also, there is a substantial reduction in the amount of each length of computer paper that is wasted when a sheet is torn from the printer and printing is commenced on the next available sheet. The method of perforation and the number of perforations per inch on each line of perforations is such that paper strength and quality of printing is maintained and the perforations are invisible on photostatic reproductions.
