Laser Printers
Run the laser video located in the demos folder on the CD accompanying this book to view a presentation of laser printers.
The laser printer has become the dominant form of computer output device, with models ranging from personal, low-volume desktop printers to behemoths that fill half a room and serve hundreds of users, churning out reams of pages every day.
All laser printers follow one basic engine design, similar to the ones used in most office copiers. They are non-impact devices that precisely place a fine plastic powder (the toner) on paper. Although they cost more to purchase than most ink-jet printers, they are much cheaper to operate per page, and the "ink" is permanent. (Most ink-jet images are, at best, water-resistant.)
