Download
Transfer information from one device to another. Downloaded fonts and
emulations are not built into the printer. They are transferred from the
computer and temporarily stored in the printer's memory (until the printer
is turned off) or on a hard disk.
dpi
An acronym for dots per inch, a measurement unit used to indicate printer
resolution. Your QMS 2425/2425
TURBO Print System has 300x300
(standard), 600x600 (standard), and 1200x1200 (optional) dpi resolution.
Driver
See printer driver.
DTR/DSR
An acronym for Data Terminal Ready and Data Signal Received, a hard-
ware-controlled protocol. It controls the flow of data via signals on the DTR/
DSR line, as opposed to XON/XOFF protocol, which is software controlled.
Electrophotographic Drum
A drum in the toner cartridge that is sensitive to both light and electricity. It
is used in the creation and transfer of images to the printed page. See also
toner, toner cartridge.
Emulation
Software that allows the printer to respond to commands intended for a
different type of printer. For example, when the printer is set for HP PCL
emulation, it responds to the same commands (HP PCL) that a Hewlett-
Packard LaserJet printer does.
Emulation Card
See font card, and security card.
Emulation Sensing Processor (ESP) Technology
Using a form of artificial intelligence, ESP technology analyzes incoming
file data from any of your printer's interfaces, selects the appropriate printer
language from those installed on the printer, and processes the print job.
ESP technology works with most popular commercially available applica-
tions.
