Random Access Memory (RAM)
The working memory of the computer in which programs and data are temporarily stored
while you use them. Resetting or shutting off the computer clears all information from RAM.
Printing very complicated documents might require closing other running programs or adding
more RAM to the computer. See also Physical RAM, Virtual memory.
Resolution
The density of dots for any given output device, expressed in terms of dots per inch (dpi). Low
resolution causes font characters and graphics to have a jagged appearance, but prints faster
than higher resolutions. Higher resolution provides smoother curves and angles as well as a
better match to traditional typeface designs, but prints more slowly. This printer can produce
output with 300 or 600 dpi resolution. Resolution values are represented by horizontal data
and vertical data, for example, 600 x 600 dpi.
Reverse Output Order
This function allows printing pages of the document in reverse order: from the last page to the
first page.

Scalable fonts
Scalable fonts allow characters to be printed in various sizes and rotation angles. This is
different from bitmap fonts, which are printed in fixed sizes and angles.
Scaling
Enlarging or reducing the printed image.
Separator page
Optional pages printed at the beginning of each document to help separate one print job from
another.
Server
A network computer that is directly attached to the printer. The server controls the printer and
handles print jobs sent from the clients. See also Client.
Shielded
A type of cable that contains a metallic sheath over the conductor material to protect the data
passing through the cable from electromagnetic interference. You need to use a double-
shielded interface cable with this printer.
Spooling
A process by which an application sends a document to the Spooler, rather than directly to the
printer, thus freeing the computer and application for other tasks. Spooled documents are
printed in the order they are received.
