Starkweather invents a process for printer high-quality text and graphics: – Computer-Laser-Printer

HISTORY OF World’s 1st Computer-Laser-Printer

Laser Printer - Complete History of the Laser Printer
World’s First Laser Printer

In 1969, while everyone else was experimenting with LSD, Gary Starkweather was hard at work at Xerox’s research facility in Webstar, New York, experimenting with the Computer-Laser-Printer. Two years later, starkweather, who has since won an Academy Award for his work with Pixar on film input scanning, constructed the first working laser printing system.


Computer-Laser-Printer uses LED – technology to obtain small particles of toner from a cartridge onto paper.

The laser printer relies on the concept that – like magnets-opposited attract. The laser Printing process begins with the laser applying the desired pattern on the revolving printer drum. The beam reverses the drum’s positive charge, making certain areas negatively charged. These negatively charged areas attract toner, a positively charged powder.

After a wire applies a strong negative charge to the printing paper, a rolling belt feeds the paper past the drum. The paper pulled the toner from the drum. The paper is neutralize its charge. Before the paper can be ejected. Paper needs to go through the fuser. This is a pair of heated rollers that melt the toner powder, thus fusing it onto the paper. The only thing that saves the paper from incineration at the hands of these rollers is the speed at which it flies through them.

Xerox failed to see the potential of the laser printer, however, discouraging starkweather from pursuing his invention. Even when they finally began producing commercial models, Xerox missed business prospects abounding in the sale of toner and paper. Hewlett-Packard began selling the world’s first personal laser printer in 1980, leaving Xerox in their toner dust.

The Interior of a Xerox laser printer from 1986; laser printers were not commonly used until the 1990s.
