What printer is, the characteristics, and the pictures of many kinds of printer? Check this presentation out.

1. PRINTER

2. • Printer is an output devices that produces printed data
on paper as the medium
• Printer is devided into two groups, that is impact and
non-impact
• Impact printer is a printer that produces a letter or
image using in physical types.
• Types of impact is dot matrix(that the result as group of
dot shapes or like a characters) and daisy wheel(letter
printing resembles a type writer).
• Non-impact printer is printer that produces a letter or
image not by using physical type, but by using ink or
toner.
• Two types of non-impact printer is inkjet printer(using
ink) and laser printer(using toner).
DEFINISION OF
PRINTER

3. HISTORY OF PRINTER
• In 1938, Chester Carlson invented a dry printing process called
electrophotography commonly called a Xerox, the foundation technology for
laser printers to come.
• The original laser printer called EARS was developed at the Xerox Palo Alto
Research Center beginning in 1969 and completed in November, 1971. Xerox
Engineer, Gary Starkweather adapted Xerox copier technology adding a laser
beam to it to come up with the laser printer. According to Xerox, "The Xerox 9700
Electronic Printing System, the first xerographic laser printer product, was
released in 1977. The 9700, a direct descendent from the original PARC "EARS"
printer which pioneered in laser scanning optics, character generation
electronics, and page-formatting software, was the first product on the market
to be enabled by PARC research."
• According to IBM, "the very first IBM 3800 was installed in the central accounting
office at F. W. Woolworth’s North American data center in Milwaukee,
Wisconsin in 1976." The IBM 3800 Printing System was the industry’s first high-
speed, laser printer. A laser printer that operated at speeds of more than 100
impressions-per-minute. It was the first printer to combine laser technology and
electrophotography according to IBM.

4. THE CHARACTERISTICS AND THE EXAMPLE OF
PRINTER
• Dot matrix printer uses iron plates, which create small
dot or square that join to make graphics and text. If
the machine produces 350 dots the quality will be
better.
• That has numbers and letters which can be raised and
arranged on a wheel that looks like aster.
• That can prints an images or character, using a small
snout that can spray ink on paper. The ink store to the
fifty chambers under the snout. These colors are
produced from the mixture of the four color.
• Use laser to change binary data to the printing result.
Can print many pages and all of the pages in a short
time.
