— JDE. Job descriptor entry commands provides you with
control over the mechanics of a particular print job. JDE
commands specify the feed and output trays, simplex or
duplex printing, stapling, and collating.
— DJDE. Dynamic job descriptor entry commands enable
you to modify the printing environment dynamically.
These commands are inserted into the input data stream
to modify the command characteristics of the existing
JDE currently in use. DJDEs can take effect on a report-
to-report, page-to-page, and record-to-record basis.
— CME. A Copy Modification Entry command allows you
to replace certain parts of a report with predefined static
data on selected copies or to specify font and ink
changes within the variable data.
Page-description and report data from host-resident software is
sent to the printer in a form that it understands and no additional
formatting commands are required.
Many host-resident software packages communicate with the
printer in a standardized page description language called
Interpress, developed by Xerox for Ethernet network-based
printers.
The 4890 LPS also supports two similar page description
languages: PostScript and the Hewlett-Packard Print Control
Language (HP-PCL) with the optional front end processor. Many
popular software applications use these languages for
communicating with printing devices.
The features available depend on the capabilities of the software
package you are using.
Color mapping
Some page composition software applications give you the ability
to specify colors based on a red-green-blue (RGB) model (or
other standard model, like cyan-magenta-yellow-black [CMYK] or
hue saturation brightness [HSB]), providing a much larger range
of colors than the printer is capable of reproducing. In these
cases, and when full color Interpress or PostScript masters are
sent to the printer, colors are automatically mapped into tones of
the highlight primary.
For Interpress, the controller attempts to make the closest
possible match between the color specified using the full-color
model and an ink in the currently available ink catalog. For
PostScript, the front end performs this function.
The 4890 is designed to fulfill the potential of efficiency
promised by electronic printing.
Speed The high output rate of the 4890, and other Xerox high-speed
laser printing systems makes it possible to bypass the separate
duplication process required in traditional printing. With an
