Glossary
AirPrint
A technology used by iPod, iPhone, iPad, and (optionally) Mac OS X 10.7 onwards, which allows immediate printing to a
printer in the same network without the need for a printer-specific driver.
AppleTalk
A suite of protocols that Apple Computer developed in 1984 for computer networking. Apple now recommends TCP/IP
and Bonjour networking instead. HP Designjet printers no longer support AppleTalk.
Bonjour
Apple Computer's trade name for its implementation of the IETF Zeroconf specification framework, a computer network
technology used in Apple's Mac OS X from version 10.2 onwards. It is used to discover services available on a local area
network. It was originally known as Rendezvous.
Color accuracy
The ability to print colors that match the original image as closely as possible, bearing in mind that all devices have a
limited color gamut and may not be physically capable of matching certain colors precisely.
Color consistency
The ability to print the same colors from a particular print job from print to print and from printer to printer.
Color model
A system of representing colors by numbers, such as RGB or CMYK.
Color space
A color model in which each color is represented 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 applications, uncontrolled electrostatic discharges are
one of the main hazards to electronic products. Therefore, to prevent damage some precautions are needed when
setting up the printer, 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 printer (mainly metal parts) before handling ESD sensitive devices (such as the printhead 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.
Fast Ethernet
An Ethernet network capable of transferring data at up to 100,000,000 bits/second. Fast Ethernet interfaces are capable
of negotiating slower speeds when required for compatibility with older Ethernet devices.
