PDL features and functions

1. 1Overview

This chapter provides an overview of PDL related information you will need in order to effectively utilize the PDL capabilities.

Print Description Language (PDL) is used to descr ibe printing jobs t o a Xerox laser printing system (LPS). PDL accomplishes this by:

• Describing the input (type, format, characteristics)

• Describing the processing functions (logical processing)

• Describing the output (type, format, font selection, accounting

options).

Diverse application needs can be met because PDL enables you to:

• Change and mix font types on a page-to-page, line-to-line, or

character-to-character basis. Output can be customized for specific needs, for example, highlighting important headings by changing font styles and sizes.

• Change page orientation and positioning on a page-to-page

basis. Characters may be printed horizontally or vertically with equal ease. The printing system switches instantly bet w een horizontal and vertical page formats, combining the two styles within a single report.

• Print a number of previously separate logical pages on the

same physical page of a document.

• Modify documents on a copy-to-copy basis by printing selected

portions of data on a page-to-page basis. You can replace certain portions of text with other data, delete paragraphs from some copies, or label other copies "confidential.

• Merge variable print data with forms stored on the system disk.

This eliminates the need for forms overlays and most preprinted forms, as well as assuring perfect registration.

• Add data, position it on the page, and print it on a variety of

forms in one job. Multiple forms, stored in digital format, are changeable on a page-to-page or copy-to-copy basis.

• Print two different forms back-to-back (duplex) on one sheet of

paper, therefore reducing paper costs. Additionally, this option offers potential savings in inventory, filing, storage, and mailing costs for computer-generated material.

• Feed paper either short-edge first or long-edge first to

accommodate a wide variety of paper sizes.

Before discussing PDL commands in detail, a general understanding of LPS components and functions is helpful. The following sections provide such a general overview.

OVERVIEW

LPS component types

Hardware

Software

LPS components consist of hardware and software.

Hardware refers to all the physical components of the LPS. Examples are the tape drives, the keyboard display, the highcapacity feeder-stacker, and the physical subsystems of the syst em controller and the printer. Refer to your

DocuPrint 96MX LPS Operator Guide

hardware components of your LPS.

Software refers to all coded instructions (programs) which are executed by the LPS. Some programs interface with LPS hardware, some with LPS firmware, and some with other software. Examples are the LPS operating system, the PDL compiler, and the output task.

OVERVIEW

The hardware components consist of the Advanced Image Subsystem (AIS).

The Advanced Image Subsystem (AIS) consists of three printed wire boards which contain character dispatcher, font and graphic memory. The three boards read the character and image data and convert it into video format for printing. With AIS, imaging a page is a two-stage process performed by the hardware/firmware combination:

64-megabit memory called a ”page buffer.” The entire page is processed and stored into this memory resulting in a bitmapped image.

are sent, one scan line at a time, to the laser. Two page buffers enable one page’s video to be ”filled“ into one

buffer at the same time that the previous page’s video is being ”dumped” from the other page buffer.

OVERVIEW

LPS software componen ts

The LPS operating system software (OSS), housed in the system controller, runs both background and foreground processing. The

major programs or “tasks” run by the system controller are shown in their hierarchical relationships in the list below. The OSS tasks are:

• Operating system executive (OSEXEC ) task

• File control program (FCP)

• Operator communication subsystem (OC S)

• Diagnostic tasks

• System util it ie s

• Editor task

• Font editor task

• Input processing task

• Ink catalog search (ICS)

• File transfer (XFR)

• Report processing (RPT)

• Memory control program (MCP)

• Termin al a nc illary contro l program (TACP)

• Ancillary IOT monitor program (AIM)

• Dynamic job descriptor (DJD) task

• Interpress decomposer (IPD) task

• Output processing task

• Print description language (PDL) processor

• Forms description language (FDL) processor

• Host interface processor (HIP) task.
