1. LPS overview
The Xerox 4050/4090/4450/4650 Laser Printing System (LPS) are
versatile, high-performance printing systems which process and
print data from a variety of sources. They allow host mainframe
computers and devices connected to a network, such as
workstations and graphic scanners, to produce publications and
other documents, incorporating graphics, forms, logos,
signatures, and a variety of fonts.
The LPS offers management information systems and data
processing environments a high-performance printer with built-in
intelligence. This feature eliminates the need for the host
computer to store and manage forms, fonts, and other document
resources.
A variety of fonts ranging in size from 4 to 24 points, in all four
orientations (portrait, inverse portrait, landscape, inverse
landscape), and many publishing typefaces are available to meet
your printing requirements. You can use special or customized
fonts developed by the Xerox Font Center in addition to the
standard set of fonts you receive with the LPS.
Table 1-1 lists the feature differences among the 4050, 4090,
4450, and 4650 LPS.
Table 1-1. LPS features

XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE 1-1

OVERVIEW
•Compatibility with the 4850 LPS enables you to use your
4050/4090/4450/4650 LPS as a suitable backup for your 4850
HighLight Color LPS. This allows you to use your
4050/4090/4450/4650 LPS to process and print highlight color
jobs in black and shades of gray.
•Limited compatibility with the 4135 LPS enables your
4050/4090/4450/4650 to process the data stream from your
4135 LPS. When your 4050/4090/4450/4650 LPS encounters a
4135 unique feature, it ignores the feature and processes the
job. A message at your system controller terminal notifies
you of the unsupported feature and gives you the
opportunity to continue or end the task.
•4245 emulation using channel connections to an IBM host
emulates an IBM line printer.
Electronic printing
Electronic printing is the integrated production of documents on
demand, using digitally stored documents and graphic images,
computerized composition techniques, and electronic printing
systems such as the 4050/4090/4450/4650 LPS.
Electronic printing allows you to use a variety of printing
applications and produce complex documents ranging from
books and lengthy reports to invoices, statements, forms, and
listings.
Advantages
Electronic printing has several important advantages over
traditional printing methods:
•Minimizes the use of preprinted forms in listings, statements,
invoices, and so on. You can create forms electronically,
using a wide range of design elements such as lines, boxes,
graphic images, and a variety of fonts. You can then
automatically merge the forms with variable data.
•Electronic printing lets you create documents and forms in a
shorter time with greater control over the result, including
the ability to make last-minute changes.
•By giving operators and programmers the capability to
program the print job processing, repetitive jobs are handled
easily and consistently, and the output potential of the
printer can be maximized.
•The programming capability, combined with a variety of
hardware configurations, makes it possible to produce
documents with cover-to-cover control. For example, you
can print different pages of a report on different paper
stocks, and the output can be collated or stapled. Electronic
printing eliminates the separate handling and finishing
process of traditional printing.

OVERVIEW
Printing data
The 4050/4090/4450/4650 LPS can print the types of data shown
in table 1-5.
Table 1-5. Data types
Data type Description
Variable data Variable data changes from page to page. The LPS can merge
variable data with a form.
Fixed data Fixed data (FRM file) remains constant from page to page (for
example, letterheads and column headings). Forms data usually
refers to information found on preprinted forms or overlays.
Note: Generating forms at a host requires a host-resident forms
design software package such as Host Forms Description
Language (HFDL).
Any form suitable for computer printout can be described and
entered into system storage. Once stored on the system, a
form can be activated by referencing the name of the form in
the Job Source Library (JSL) file or Job Descriptor Entry (JDE).
All Xerox laser printing systems have a line editor utility for the
creation and modification of program source files (.FSL and .JSL
extension files).
Refer to the Xerox 4050/4090/4450/4650 LPS Command
Reference for more information on the LPS Editor.
Graphic data
(usually merged
with variable data
or fixed data)
Graphic data (.IMG file) refers to digitized images (both line art
and continuous tone images) that are merged with variable or
forms data. Sources of graphic data include the following:
•Graphic data generated by EPIC host-resident software
•Scanned images from the Xerox 7650 Pro Imager (using
XPIW)
•Scanned images from the 150 GIS.
Note: The GHO/GVG option is required on the LPS to process
graphic data.
Production process overview
The process of producing a job on an LPS can be broken down
into three distinct phases: input, special processing, and output.

As shown in figure 1-2, several data input methods are available.
Figure 1-2. Xerox 4050/4090/4450/4650 input options
1-8 XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE

OVERVIEW
The input sources shown in table 1-6 are available for the
4050/4090/4450/4650 LPS.
Table 1-6. Input sources
Input source What it does . . .
Channel-attached
host The online channel interface receives input directly from a host mainframe through a cable and supports all IBM and
IBM-compatible systems supporting the channel-attached
3811/3211 and 4245 interfaces.
Remote host The 871-CM and the OEM interface use the Host Interface
Processor (HIP) task to permit ASCII and EBCDIC data
transmission to the LPS using SNA/SDLC or BSC protocols.
This input method allows the 4050/4090/4450/4650 LPS to
print jobs from a remote IBM-compatible host computer. By
using a telephone modem, the 871-CM eliminates the need
for a channel extender unit.
VAX/VMS host The DEC interface enables communication between a DEC
VAX/VMS system and a 4050/4090/4450/4650 LPS through
cable or modem connections using the HIP task.
Refer to the Xerox Print Management Facility—VMS Version
manuals, which contain more information on DEC VAX/VMS.
Magnetic tape Magnetic tape input (9- or 18-track) is received by the offline
interface. The Xerox Laser Printing Systems Tape Formats
Manual describes the tape format and encryption schemes
that a Xerox LPS recognizes.
Workstations and
graphic scanners Using the HIP task, the ethernet interface receives input from workstations, such as the Xerox 6085, and graphic
scanners, such as the 7650 Pro Imager, using Xerox
Publishing Illustrator Workstation (XPIW) and the 150 GIS.
Ethernet is the Xerox Local Area Network (LAN) that allows
data to be transmitted by cable from one device to another
on a shared or an unshared, but accessible, network.
Note: Graphic handling requires either Graphics Video
Generator (GVG) or Graphics Handling Option (GHO) on the
4050/4090/4450/4650 LPS.
Special processing
Special processing features (outlined in table 1-7) distinguish the
4050/4090/4450/4650 LPS from an impact printer because you
can specify that you want the system to perform logical functions
(such as printing portions of the data, offsetting certain pages of
a report, and repositioning a page logically during the printing
process).

OVERVIEW
Table 1-7. Special processing features
Feature What it provides . . .
DJDE A Dynamic Job Descriptor Entry (DJDE) command allows you
to modify the printing environment dynamically. You insert
these commands into the input data stream to modify the
command characteristics of the existing JDE. DJDEs can take
effect on a report-to-report, page-to-page, and record-to-
record basis.

Description Language (PDL) Reference for more information.
CME A Copy Modification Entry (CME) command allows you to
replace certain parts of a report with predefined static data
on selected copies or to specify font changes within the
variable data.

LPS output
The final production phase is output. The 4050/4090/4450/4650
LPS provides powerful finishing and disbursement features. You
can have a cover-to-cover printing process on any job. This
means that an inventory stock report job could have:
•Blue card stock front cover with the title in a 24-point bold
font
•49 pages of equipment inventory, with the last page
designed to summarize totals
•37 pages of equipment description, with pricing information
removed, and a shaded grid filling the columns on each page
•A matching blue card stock back cover printed on the
reverse side with “END OF REPORT” in a 14-point bold font.
You can have each copy of the inventory report offset, or
stitched (stapled) and offset, in the stacker tray for easy
identification. The system places a routing sheet on top of each
offset stack. This routing sheet contains information such as
“Jones and Smith Supplies, Inc.” This feature is useful when you
want to separate individual copies for binding or distribution to
different groups.
With the bypass transport option, you can connect third-party
finishing equipment directly to your 4050/4090/4450/4650 LPS.
The bypass transport fits into tray 1 of the dual stacker output
module configuration. Third-party devices do a variety of
finishing tasks such as saddle stitching, binding, folding, stapling,
trimming, and stacking.
