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 10.2 and later. Use it to discover the services that are

available on a local area network (LAN). It was originally known as Rendezvous.

CALS/G4

CALS (Continuous Acquisition and Life-cycle Support) is an initiative of the US Department of Defense for

electronically capturing military documentation and linking related information. The initiative has developed a

number of standard specifications (protocols) for the exchange of electronic data with commercial suppliers. These

standards are often referred to as simply "CALS". CALS standards have been adopted by several other allied

nations.

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 expectan+cy 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.
