Technology
Canon's heritage of technological innovation and ease-of-use
combine with its ability to offer affordable products that address specific needs
of the consumer will continue to be the foundation of the company's success. One
of the key factors, which Canon uses to differentiate itself in the competitive computer
peripherals market is its proprietary technologies.
Canon is unique from its competitors in two ways:
It develops its own technology, whether it Is Bubble Jet, imaging, optics, inks or
media; and, it integrates these technologies to achieve innovation leadership and
sales success.
Canon believes the future of high quality, affordable
computer printer output lies in Bubble Jet technology, a unique and versatile printing
process that Canon introduced in the early 1980's. Holding more than 10,000 patents
for Bubble Jet technology alone, Canon's Bubble Jet printers have been the major
contributor to our aggressive success.
Today, the technology is used in our complete line
of affordable Bubble Jet printers that produce laser-quality monochrome and photo-quality
color reduces costs output. With more than 550 research and development personnel
in Japan devoted to constantly enhancing Bubble Jet technology, Canon continues to
create new products, which showcase Bubble Jet technology's quality, reliability
and flexibility.
Canon's Bubble Jet technology is being used in the
world's first seven-ton textile printing system jointly developed in Japan with Canon
Inc. and Kanebo Ltd., that automates, simplifies and greatly reduces costs associated
with color textile printing for the Japanese market.
Terminology
AppleTalk
AppleTalk is a set of local area network communication
protocol originally created for Apple computers. An AppleTalk network can support
up to 32 devices and data can be exchanged at a speed of 230.4 kilobits per second
(Kbps). Devices can be as much as 1,000 feet apart. AppleTalk's Datagram Delivery
Protocol corresponds closely to the Network Layer of the Open Systems Interconnection
(OSI) communication model.
Dpi
In printing, dots per inch (dpi) is the usual measure
of printed image quality on the paper. The average personal computer printer today
provides 300 dpi or 600 dpi. Choosing the higher print quality usually reduces the
speed of printing each page.
Hue
Hue, saturation, and brightness are aspects of color
in the red, green, and blue (RGB) scheme. These terms are most often used in reference
to the color of each pixel in a cathode ray tube (cathode ray tube) display. All
possible colors can be specified according to hue, saturation, and brightness (also
called brilliance), just as colors can be represented in terms of the R, G,
and B components.
Saturation
Saturation is an expression for the relative bandwidth
of the visible output from a light source. In the diagram, the saturation is represented
by the steepness of the slopes of the curves. Here, the red curve represents a color
having low saturation, the green curve represents a color having greater saturation,
and the blue curve represents a color with fairly high saturation. As saturation
increases, colors appear more "pure." As saturation decreases, colors appear
more "washed-out."
Brightness
Brightness is a relative expression of the intensity of the energy output of a visible
light source. It can be expressed as a total energy value (different for each of
the curves in the diagram), or as the amplitude at the wavelength where the intensity
is greatest (identical for all three curves). In the RGB color model, the amplitudes
of red, green, and blue for a particular color can each range from 0 to 100 percent
of full brilliance. These levels are represented by the range of decimal numbers
from 0 to 255, or hexadecimal numbers from 00 to FF.
Printer Control Language
Printer Control Language is the standard printer language for laser printers. PCL
is used for printing letters, database printouts, spreadsheets, and simple graphics.
Postscript
Postscript printers are used with desktop publishing software and drawing packages.
Postscript printers are the norm for Apple Macintosh printers. A laser printer that
comes with Postscript installed is more expensive. The application being used must
support Postscript in order for the laser printer to print Postscript documents.
