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.
