Decimal

(based on the number 10).
DIP Switch (Dual Inline Package)
A DIP switch is an electronic component, of-
ten a series of small switches. It serves to pre-
set the printer.
Dot
The smallest addressable unit in bit maps.
One bit is assigned to every dot. The bit can
have the value 1 for black (set dot) or 0 for
white (non-set dot).
Dot Matrix Printer
The print characters are made up of dots (dot
matrix). The needles strike the colour ribbon
onto the paper and produce a dot. Depend-
ing on the number of pins 9-, 18- and 24-pin
printers are distinguished. The needles are
arranged in one or two columns. Common
needle diameters are 0.3 mm for 9-pin print-
ers and 0.2 mm for 24-pin printers The reso-
lution depends on the needle size, it defines
the typeface.
dpi (dots per inch)
The graphic resolution is given in dots per
inch. Usual resolutions for needle printers
are between 60 and 288 dpi.
Driver
See »Printer Driver«.
Duplicates
With print-sensitive paper or duplicating pa-
per with carbon duplicates (copies) can be
made, because the printing is performed by
stroke. Three duplicates for 24-pin printers
and four duplicates for 9-pin printers are
common.
Emulation
Emulation means that the functions of a de-
vice are imitated, for example the printer
functions of the IBM ProPrinter. In general,
your dot matrix printer offers additional
commands and printer functions apart from
the given options which can be made availa-
ble by selecting the correct printer driver.
Epson Emulation
In the selected emulation the printer imitates
the chosen printer type and performs the
print commands of an Epson LQ printer (24
needles), for example.
Escape (ESC)
Escape is a non-printable control character of
the ASCII character set (decimal 27, hexadec-
imal 18). Most print commands are initiated
by the Escape-character.
FF
See »Form Feed«.
Font
A font is defined by the combination of dif-
ferent characteristics such as print quality or
character spacing.
Form Feed (FF)
This printer command terminates one page
and outputs it. By pressing the FF-key a form
feed can be performed manually.
Hexadecimal
A term for a digit of the hexadecimal system
(with a base of 16). The figures 0 to 9 and ad-
ditionally the letters A to F (for the numbers
