Resolution
The 4850/4890 NPS/IPS provides high print quality at 300 dpi
resolution. It can receive data at 240, 300, or 600 dpi. The
controller converts 240 and 600 to 300 dpi data.
The 92C NPS/IPS provides exceptional print quality at 600 dpi
resolution. It can receive data at 240, 300, or 600 dpi. The
controller can convert incoming data to 600 dpi for printing, or
can convert the data to 240 or 300 dpi and allow the print engine
to convert the pages to 600 dpi.
The following table shows how data streams of different
resolutions are interpolated.
NOTE: For more information on specifying appropriate
resolution settings, refer to the Guide to Managing Print Jobs
and the Guide to Configuring and Managing the System. For
IPDS printing, refer to the to Solutions Guide for IPDS printing.
System components overview
DocuPrint NPS/
IPS
The entire DocuPrint NPS/IPS system includes the printer (also
known as an IOT or print engine), printer controller, printer
interface, and all appropriate software. “DocuPrint printer” or
“printer” refers to the base printer engine (IOT) only, without the
printer controller and interface.
Xerox-supplied
printer controller
The printer controller includes a processor, DVD-ROM (or CD-
ROM) drive, diskette drive, keyboard, mouse, and a monitor. The
printer controller accepts the print job from the client workstation
or host, converts the files into page images, and sends the page
images to the printer. The user interface at the printer controller
allows you to perform tasks such as monitoring job status,
prioritizing jobs, and configuring the system.
