Glossary of selected Xerox terms

C
CMD: The file type, or extension, of a Xerox command file. These text files contain command-language statements for groups of related commands. The commands can perform tasks, such as setting up a printing environment and running a specific job. Then, the operator can run all of the commands in the CMD file by entering its name as a single command, rather than having to enter all of the commands individually.
CME: See Copy Modification Entry.
Copy Modification Entry (CME): The file type, or extension, of a Xerox copy modification entry. A CME contains text changes or font changes to make at a specific location on the page. The change can occur on all copies of a job, or only on specific copies. For example, you can use a CME to replace or highlight text on line eight of page three on copy two.
copy-sensitive: A report that has multiple, collated copies, with CMEs, FORMS, or BFORMs that are applied to specific copies. For example, you can request three copies of a particular report and specify that copy one of the report use CME1, and that copies two and three use CME2. Likewise, in a report with six copies, you can request that FORM1 appear on copies one through four, and that BFORM2 be printed on the backs of copies three through six. The Xerox LPS processes copy-sensitive CMEs only in the offline environment. In online jobs, copy-sensitive specifications for CMEs are ignored, and the CMEs apply to all of the copies. You can specify copy-sensitive FORMS and BFORMs for both online and offline jobs.

D
DJDE: Dynamic Job Descriptor Entry.
Dynamic Job Descriptor Entry (DJDE): Commands within an input file for a Xerox LPS printer. The Xerox printer uses these commands to dynamically modify the printing environment. DJDEs can be page-oriented or record-oriented, which determines when they take effect. For example, DUPLEX, COPIES, COLLATE, FORMS, and SHIFT are representative of page-oriented commands.
downloadable PDE: A DJDE that begins with 'FORMAT=*' and that contains a list of fonts in a binary format. Xerox developed the downloadable PDE for use with early versions of Xerox printer software. Although the FONTS DJDE currently replaces it, later Xerox printer software versions still support it. XICS and HFDL programs can optionally generate downloadable PDEs when producing metacode output. The FORMAT=* DJDE might also be found in metacode that programs written by Xerox customers produce.

E
Electronic Printer Image Construction (EPIC): A Xerox host-resident software product (MVS/VM) that transforms graphics files into Xerox compressed raster image format for printing on an LPS printer that has the graphics handling option (GHO) installed. Interfaces are provided to Dassault System of America’s CADAM, ISSCO’s DISSPLA/TELL-A-GRAF, SAS Institute’s SAS/Graph, GDDM®, and DCF.
EPIC: Electronic Printer Image Construction.

F
FDL: Forms Description Language.
FNT: The file type, or extension, of a Xerox font file. Infoprint XT converts Xerox FNTs into AFP fonts.
form: A Xerox form is a collection of predefined data, stored on the printer hard disk, such as lines, shading, graphics, and text, that can be merged with variable data on a sheet while printing.
Forms Description Language (FDL): A command-oriented language that enables the user to create forms by specifying such things as page orientation, font selection, and rules. Customers use FDL commands by inputting them through the Xerox LPS printer console. FDL is also the Xerox LPS compiler task that creates FRMs from FSLs. Infoprint XT does not use FDL commands in data-stream conversion. It uses the actual form, as specified in an FRM file.
Forms Source Library (FSL): A file that contains FDL source statements that define one or more electronic forms. Infoprint XT does not use FSLs during data-stream conversion.
FRM: The file type, or extension, of a Xerox form file. Infoprint XT converts Xerox FRMs into AFP overlays.
FSL: See Forms Source Library.

G
GHO: Graphics Handling Option.
Graphics Handling Option (GHO): A collection of hardware and software that enables Xerox LPS printers to print graphic images, in addition to text and forms.

H
HFDL: Host Forms Description Language.
Host Forms Description Language (HFDL): A Xerox host-resident software product (on MVS™ and VM) that customers use to create electronic forms for Xerox LPS printers. The printer software (microcode) shipped with the Xerox LPS printer includes a printer-resident version of the software.

I
ICT: Ink Catalog.
IDR: Ink Description Entry.
IMG: The file type, or extension, of a Xerox image file. Infoprint XT converts Xerox IMGs into AFP page segments.
Ink Catalog (ICT): The object file that contains descriptions of Xerox highlight color palettes and inks.
Ink Descriptor Entry (IDR): A Xerox LPS printer file that specifies default highlight color ink catalogs, palettes, and inks.
Ink Source Library (ISL): A Xerox LPS printer source file that contains statements that define highlight color palettes and inks.
inline resources: In a Xerox printing environment, all resources, such as fonts and graphics, reside on the Xerox printer. Xerox printers can accept jobs that specify FILE or GRAPHICS DJDEs, which cause new resources to load on the printer. In some cases, the incoming job contains no print data, but rather contains resources that load on the printer when the job runs.
inverse landscape orientation: The position of printed data on a sheet of paper, 180° from standard landscape orientation for a device.
inverse portrait orientation: The position of printed data on a sheet of paper, 180° from standard portrait orientation for a device.
ISL: Ink Source Library.

J
JDE: Job Descriptor Entry.
JDL: Job Descriptor Library.
Job Descriptor Entry (JDE): A set of print-job characteristics grouped together to represent the processing requirements for a specific print job. These are also known as job command sets. You can define one of the JDEs as the default job descriptor entry. You can use the default JDE to establish a default print environment, which the actual print job can dynamically altered through embedded DJDE statements.
Job Descriptor Library (JDL): The object file created by compiling the JSL, which contains one or more JDEs to use on a Xerox LPS printer.
Job Source Library (JSL): A Xerox LPS printer source file that contains statements that define the characteristics of one or more print jobs (JDEs). The characteristics can include tape formats for tape to print, logical processing requirements, and output formats, such as COPIES, OFFSET, DUPLEX, SHIFT, and FORMS. In order to run Xerox print jobs, the JSL must first be translated into object form, a compiled JDL, by the printer control unit. JSLs can also define other print environment control resources, such as CMEs, PDEs, and STKs.

L

Laser Printing System

A class of Xerox cut-sheet production printers that accept LCDS jobs and metacode jobs. Most of the LPS printers, such as the 4635, are in the DocuPrint series of printers.

LCDS

Line Conditioned Data Stream.

LGO

The file type, or extension, of a Xerox logo file. Infoprint XT converts Xerox LGOs into AFP page segments.

LIB

The file type of a Xerox 80-byte text file, or a cluster library file (not in 80-byte text format). Infoprint XT processes and uses information in the CLUSTR.LIB file. This file correlates clusters, which are individual paper drawers or groups of paper drawers, with names of paper drawers or paper drawer groups. STK files contain the name definitions.

Line Conditioned Data Stream (LCDS)

Line data with imbedded DJDEs that specify formatting instructions for the data.

line data

A data stream format that contains standard text and impact printer controls, such as channels and carriage controls. Line data contains no metacodes or DJDEs.

logical page

An imaginary rectangular section of a physical side of a sheet. By using the BEGIN command, a Xerox print job can specify that several logical pages exist on each physical page. Xerox data streams typically use skip-to-channel-1 carriage controls to jump from one logical page to the next. When data for all of the logical pages on one side has been processed, the next skip-to-channel-1 carriage control causes the printer to jump to the first logical page on the next side.

logical processor commands

Special Xerox commands that look for predefined character strings or character-string changes in the input data, and take various kinds of action when one of the strings is found. The logical processor commands include:

BANNER: Detects banner pages. It might pick off some of the information on the banner pages for accounting purposes, or it might delimit reports within a print job.
BDELETE: Deletes specified blocks from offline data, to prevent them from printing.
BSELECT: Selects specified blocks from offline data, to cause them to print.
RAUX: Pulls a single sheet of paper from the auxiliary paper tray.
RDELETE: Deletes specified records from offline data, to prevent them from printing.
RFEED: Dynamically specifies a cluster of input paper drawers.
ROFFSET: Causes the paper to jog in the output tray.
RPAGE: Moves the next or current logical page to the back of the current sheet, or to the front or back of the next sheet.
RRESUME: Resumes printing after a group of records when the contents of the first and last records are known, but the contents of the records between them are not.
RSELECT: Selects specified records from offline data, to cause them to print.
RSTACK: Delimits reports within a print job, and restores the starting JDL / JDE environment.
RSUSPEND: Prevents printing of a group of records when the contents of the first and last records are known, but the contents of the records between them are not.

LPS

Laser Printing System.

M
metacode data stream: A data stream containing imbedded metacodes. It might or might not also include DJDEs. Some Xerox host system software products, such as XICS, produce output with imbedded metacodes. Additionally, some Xerox customers have written applications that embed metacodes in the print file.
metacodes: Metacodes are a specific set of reserved, single-byte character codes. These codes convey formatting instructions to the printer. You can think of the metacode format as the native language of the Xerox LPS printer.

N
non-printable resources: In Infoprint XT, Xerox resources for which Infoprint XT creates only metrics data sets during the resource loading process. Xerox PDE and JDL resources are examples of non-printable resources. Contrast with printable resources.

O
offline environment: In an offline printing environment, the Xerox printer receives the incoming data from a tape drive attached to the printer, rather than from a channel-attached host. This environment requires operator intervention to send the data to the printer.
online environment: In an online environment, the printer receives the incoming data directly from a channel-attached host. This environment requires no operator intervention to send the data to the printer.
OTEXT: A type of job that contains messages for the operator. The messages display on the console of the printer. For example, the message might specify the type of paper to load.

P
Page Description Entry: A set of statements that define formatting information for each page of a print job, including page orientation, starting print line, and fonts.
page-oriented DJDE: A DJDE that takes effect on the next skip-to-channel-1 in the input file.
PDE: Page Description Entry.
PDL: Print Description Language.
PDL compiler: A printer, workstation, or host-based program used to translate PDL source commands into objects that the Xerox LPS can use.
Print Description Language: Statements that define the characteristics of print jobs, such as tape formats for tape to print, logical processing requirements, and output formats. You use these statements to create CMEs, PDEs, JDLs, and so on.
printable resources: In Infoprint XT, Xerox resources for which Infoprint XT creates both metrics data sets and AFP data sets during the resource loading process. Xerox fonts, images, logos, and forms are printable resources. Contrast with non-printable resources.

R
record-oriented DJDE: A DJDE that takes effect on the next input file record.
report: In Xerox terminology, a logical subset of the data in a Xerox print job. Each print job might consist of a single report, or might contain several reports. Delimiter pages might separate reports in the printed output. Each report might also end with an accounting information page. Within the input data stream, character strings defined by the RSTACK or BANNER command serve to separate the reports.
resource (Xerox definition): A collection of printing instructions, and sometimes print data such as fonts, forms, images, and logos that can be divided into the categories public, private, and restricted. In the Xerox environment, these resources reside on the printer hardware. See non-printable resources and printable resources. For the AFP definition of this term, see Glossary of selected IBM terms.

S
signature font: A font containing one or more images, logos, or signatures that are tiled into multiple characters. Printing the correct sequence of characters from the font can reproduce the image.
START: The START command that a Xerox printer operator uses to start a print job from the console of a Xerox LPS printer. The command has two arguments, separated by a comma. The first argument is the JDE for the job, and the second argument is the JDL. Each job must specify the appropriate starting JDE and JDL, otherwise the job either does not print or prints with errors.
STK: The file type, or extension, of a Xerox stockset file. A stockset file defines paper drawers, such as which are the main and auxiliary drawers, and which is the default drawer. You use STK files in conjunction with the cluster database (CLUSTR.LIB), which contains cluster information in a binary format. The stockset and the CLUSTR.LIB represent a printing environment when the operator has loaded specific types of paper in the drawers of the printer. For example, when printing checks, the customer might have monthly-statement forms in one drawer, and the actual checks in another drawer.

T
TST: The file type, or extension, of a Xerox routing text file. These precompiled files contain text strings that print on separate pages that precede individual reports. These text strings are also called routing text, and they might optionally print with an overlay. You compile TST files from ROUTE commands in JSL files. The RTEXT JDL command, or the RTEXT DJDE in the data stream invokes them. The RFORM JDL command or RFORM DJDE specifies whether an overlay prints on the routing text page.

X
Xerox Escape Sequence (XES) data stream: A data stream format supported by certain Xerox distributed mode printers. The escape sequence is a print control character or "key" which is user-defined for each print job. Synonymous with UDK (User Defined Key). Infoprint XT does not support this data stream format.
Xerox Integrated Composition System (XICS): A host-resident software product for composing text documents (MVS/VSE/VM) that print on a Xerox centralized printer or phototypesetter. Support is provided to merge Xerox format graphic images inline or to reserve white space for merging at the printer. Commands are of the control word variety, rather than generalized markup.
Xerox Job Control Facility (XJCF): A host-resident software product developed by Xerox Computer Systems as an extension to MVS/JES2 for the Xerox LPS printers. It builds and inserts DJDE records into the output file based on user job control statements, Xerox-extended JES2 parameters, initialization parameters, and JES2 system defaults. In addition to 3800-1 compatibility support, it provides a mechanism for accessing other features of the Xerox centralized printers (such as duplex, two-up, and electronic forms merge) without user awareness of DJDEs.
Xerox Production Print Mode (XPPM): To print to Xerox LPS printers by using LCDS or metacode data streams.
