Glossary Bonjour Apple Computer's trade name for its implementation of the IETF Zeroconf specification framework, a computer network technology that is used in Apple Mac OS X V10.2 and later. Use it to discover the services that are available on a local area network (LAN). It was originally known as Rendezvous. Color accuracy The ability to print colors that match the original image as closely as possible, given the fact that all devices have a limited color gamut and might not be able to match certain colors precisely. Color consistency The ability to print the same colors in a particular print job, from print to print and from printer to printer. Color model A system of representing colors by numbers. An example of such a system is RGB or CMYK. Color space A color model in which each color is repesented by a specific set of numbers. Many different color spaces can use the same color model: for instance, monitors generally use the RGB color model, but they have different color spaces, because a particular set of RGB numbers results in different colors on different monitors. Cutter A printer component that slides back and forth across the platen to cut the paper. ESD ElectroStatic Discharge. Static electricity is common in daily life. It is the spark when touching the car door, or the cling of clothing. Although controlled static electricity has some useful benefits, uncontrolled electrostatic discharges are one of the main hazards to the electronics products. Therefore, to prevent damage some precautions are needed when setting up the product, or handling ESD sensitive devices. This type of damage may reduce the life expectancy of the device. One way to minimize uncontrolled ESDs, and therefore reduce this type of damage is by touching any exposed grounded part of the product (mainly metal parts) before handling ESD sensitive devices (such as the printheads or ink cartridges). Additionally, to reduce the generation of electrostatic charge in your body try to avoid working in a carpeted area, and keep your body movements to a minimum when handling ESD sensitive devices. Also, avoid working in low humidity environments. Ethernet A popular computer networking technology for local area networks. Firmware Software that controls your printer's functionality and is stored semi-permanently in the printer (it can be updated). Gamut The range of colors and density values reproducible on an output device, such as a printer or monitor. HP-GL/2 Hewlett-Packard Graphics Language 2: a language defined by HP to describe vector graphics. I/O Input/Output: this term describes the passing of data between one device and another. ICC The International Color Consortium, a group of companies that have agreed on a common standard for color profiles. Ink cartridge A removable printer component that stores ink of a particular color and provides it to the printhead. IP address A unique identifier that identifies a particular node on a TCP/IP network. It consists of four integers separated by dots. Jetdirect HP's brand name for its series of print servers that allow a printer to be connected directly to a local area network. LED Light-Emitting Diode: a semiconductor device that emits light when electrically stimulated. 216 Glossary
