Perry laser printer, if rated with other printers, would produce 6,720 lines per minute or 14,560 characters per minute. Directorate of ComputerCommunication Systems In 1985, one trillion pages of paper were computer generated. That's a stack of paper taller than 7,500 Mount Everests! One of the tools being used in Air Force Logistics Command to tame this "paper tiger" is the laser image is composed before printing, why not reduce the size of the printed page by reducing the font size and print two pages on 6ne image? And why not print in duplex so that we get four pages of data on one sheet of paper? The potential result of this development is staggering. We print an average of between six and seven million pages per month on our three laser printers at a cost of nearly $30,000 in paper alone. SVfc-by-ll-in- ch speed is measured in lines per minute. These printers are rated from 1,200 to 3,000 lines per minute. printer. All laser printers print one page Laser printers are the current rage in the computer peripheral market. Ever since Apple Computer introduced its desk top publishing system, more and more people are aware of this printing technology. AFLC has been using this printing method since early 1983. Originally, the major benefits of these printers were thought to be their printing speed, quiet operation and the legibility of at a time. These are rated from eight pages per minute to 120 ppm. The Xerox 9700 laser printers we have in the command are capable of printing 120 pages per minute. The typical; page has 56 lines or 7,280 characters. The laser printer, if rated with other printers, would produce 6,720 lines per minute or 14,560 characters per Using printing that has brought the laser printer into its own. Laser printers are also programmable. This means that the fonts or type of print are variable and can be programmed to the user's needs. In addition, graphics such as a form can be stored in the printer's memory and called up to be merged with the text at the time of printing. One of the most exciting develop so-call-ed High speed line printers produce a complete line at a time and so their ' would put leave and earnings statements and W-- forms on the laser, eliminating reprints when the carbons are unreadable. What does the future hold for this technology in AFLC? Firstthe current abilities of these printers will be better utilized. And the fact that these printers have the capability to print bar code, magnetic ink characters and graphics is not well known and suggests many applications. With the addition of a graphics handling option, 2 which saves valuable machine time, ink and consumables. Paper usage tracking has verified that these savings are indeed possible, and our efforts to inform users of this alternative has begun to pay- - off. Much more can be done in this area. Speed, quiet operation and legibility are great benefits, but it is the ability to compose a complete page before Dot-matri- can not only cut "two-up- " these figures in half, but it also reduces the print time by 38 percent second! their product. x These printers are fast! wheel or other printers and Daisy typewriter-lik- e printers can print one character at a time. Their print speed is measured in characters per second. Typically, these printers are rated from 40 to 180 characters per second with the "letter quality" or more legible printers being the different forms. Among those are the Form 173 cards used by maintenance personnel for work assignments and to record the time spent on a job. Each time a form can be printed when needed and its image stored in the printer's memory, significant savings result. These savings are realized because the cost to buy preprinted forms and the cost of distributing and storing these forms are eliminated. Multi-par- t forms that use carbons are prime candidates because the printer makes a new image for each copy. No more unreadable copies! A suggestion, now being evaluated, ments in the Directorate of Computer Communication Systems has been the use of "two-up.-" Since a complete TH Other projects have created ,or reproduced electronically forms to be stored and printed as output from several data systems. The J023 system, for example, prints government contracts and other forms.
