push of the default button. The default values for the firmware are
usually denoted on a label attached to the Printer.
Defrag Abbreviation for defragmenting. The process of reformatting data on
a hard Drive so that it uses space more efficiently.
DIP switches (Dual
In-line Package
Switches) A small array of mechanical switches installed on the board that can
be configured to change Printer operations including providing a
variety of self-tests.
Direct-to-Card (DTC)
Printing The Direct-to-Card printing process prints digital images directly
onto any plastic card with a smooth, clean, glossy PVC surface.
Dither A system of distributing dots to control the hue, brightness and/or
saturation. In monochrome printing, this controls the brightness. In
color printing, dithering can supply a larger color gamut than non-
dithering. In the Driver, dither modes can be selected to provide
better image quality depending on the type of image to be printed.
Dongle A peripheral that attaches to a port to act as a key for an installed
application. The PC is able to run that application only when the
dongle is installed. Typically, it works as a pass-through device and
is connected in serial to the parallel cable.
Dot The smallest unit of an image that the Printer is able to produce.
The smaller the dot, see dot pitch, the sharper the image.
Dot pitch A measurement of image sharpness denoting the width of the dots
that make up a pixel. The smaller the pitch, the sharper the image.
Download The transfer of a data file from one device to the other over a
network or cable, typically from the Internet to a PC.
DPI (Dot Per Inch) A measurement of the Printer resolution indicating how many dots a
Printer can produce in a linear inch.
DRAM (Dynamic
Random Access
Memory) A microchip based volatile memory storage device. The Printer
uses this to buffer a print job, transferred from the PC, until the
Printer contRoller is able to process the packet.
Driver Software utility installed in Windows, that interfaces an application
to rasterize image data and include command codes so the Printer
can process the file.
Duplex Printing Printing on the front and the back of the card.
Dwell Time The speed at which the card moves across the lam Roller,
measured in seconds/inch (secs/in). This may be adjusted in the
Driver to ensure adhesion and card flatness.
