What a Printer Can Do Today vs Ten Years Ago

The development of computer printers began in 1938. Early printers served big computer applications in big business. It was all a question of size. The development after the 1980s has focused mostly on serving the home desktop, a problem of size, ink cartridges, price, and customer demand.

Laser Printers
The original Xerox printers included a xerographic imaging process. But, modern laser printing peripherals use a scanning laser beam that adheres the ink to the paper. For color printing, each process requires separate passes through four primary color toners. Laser printers remain popular for high-quality color and black/white images, but size and cost discourage purchase by the average home user.

Inkjet Printers
Liquid inkjet printers dominate the home market and a good share of business needs. Inkjet technology depends on the propulsion of different-sized droplets from ink cartridges onto paper. In recent years, inkjet printers have increased in quality and speed - at increasingly low prices.
