1 Intended Audience

This document is intended for use by the AccXES software development team and other Xerox technical

personnel interested in reviewing the AccXES definition and implementation of the HP-PJL Job

Control language. Third party integrators, host client printer driver and utility developers, and related

printing system developers will also find useful information in this document. No familiarity with the

AccXES software architecture is assumed or required for understanding this document. However, the

reader should have a thorough understanding of HP-PJL as defined in Hewlett-Packard’s “Printer Job

Control Language Technical Reference Manual,” [HP96].

Persons interested in the general technology platform and requirements of the Xerox/AccXES should

refer to the “Architecture Requirements and Technologies” document also listed below.

ccXES PJL Interface

2 Introduction

Many of the data formats and page description languages supported by the AccXES architecture do not

have a mechanism to control many job processing attributes. Other languages have some job control,

but cannot control the more specialized features of the printer, such as finisher options. To access

advanced printer functionality, a separate mechanism is required. This is the responsibility of the Job

Control Language. Specifically, AccXES architecture supports HP-PJL, which is an industry standard

printer job control language originally developed by Hewlett-Packard. The specific implementation of

HP-PJL on the AccXES architecture is a superset of the core HP-PJL functionality. The HP-PJL

superset is tailored to the feature set required for the Xerox printing and plotting systems.

It is intended that this language be well documented and easily available for external third party

integrators to use in their development of host based print servers employing the AccXES controller in

the printer as well as client platform print drivers and utilities.

nother goal of the

ob control language implementation is to allow remote configuration and

control/status. All operations that can be performed at the printer front panel interface should be

available through the job control language implementation. Of course, client host software is required

to produce the appropriate job control constructs.

HP-PJL is used to encapsulate the user jobs to provide job and printer control information. In this

respect, it can be viewed as functioning “above” the level of HPGL/2, TIFF, and other printer languages.

The following figure shows how HP-PJL may be combined with user print jobs. Notice that HP-PJL

can be used independently of user print jobs as well.

HP-PJL Only Printer Control Job

Unencapsulated User Job (HPGL/2, TIFF, ...

Figure: Combinations of HP-PJL and User Jobs

ccepted by

ccXES

The use of HP-PJL is not required so that host systems with print drivers which don’t utilize HP-PJL

can still be supported; however, using HP-PJL makes the work of job segmentation and data format

detection error proof.

Examples of

ob specific control information provided by HP-PJL when encapsulating a user

include:

•

utomatic Collation

•Automatic Scaling and Rotation

•Emulation Switching (explicit or automatic)

Version 10.0

ccXES PJL Interface

•Multiple Copies and Electronic Collation

•Plot Nesting

•Job

ccounting information

•Tray and Media Selection

•Raster Stamps, Plot Overlays, Forms

•Many others...

When HP-PJL is sent independent of user print

ob, it can be used to query printer status and spool

queue information, change host interface parameters, or perform any action the user can perform from

the printer front panel. Specific HP-PJL only jobs can be sent to:

•Change printer defaults

•Configure host interfaces

•Manipulate the printer

ob queue

•Obtain printer status

•Perform printer system diagnostics

•Perform Job

ccounting administration.

•Program internal system FLASH memory

Hewlett-Packard’s “Printer Job Language Technical Reference Manual,” [HP96], provides the complete

definition of HP-PJL. Only exceptions and extensions to the standard language defined by [HP96] are

discussed in the sections that follow. This document provides a full specification of the AccXES

customizations and extensions of the HP-PJL language. The reader is urged to review [HP96] prior to

reading this document.

3 HP-PJL Commands

This section defines the HP-PJL commands that are utilized by the AccXES software architecture as

well as the custom commands defined by the AccXES architecture. A user job with custom AccXES

HP-PJL commands embedded within it is required to run without error on a standard HP-PJL printer.

In practice, this means that new HP-PJL commands are embedded within the HP-PJL COMMENT

command.

Conversely, standard HP-PJL

obs should run without error, albeit with loss of printer feature control,

on a AccXES printer. Consequently, all HP-PJL commands defined in [HP96] are implemented in

AccXES printers. The AccXES printer will most closely resemble a Hewlett-Packard LaserJet 4V/4MV

printer in its HP-PJL implementation.

3.1 Kernel Commands

The kernel commands detailed in the following sections are implemented in the

ccXES printer.

3.1.1 UEL

The UEL command will be implemented as defined on page 4-2 of [HP96]. From the HP-PJL

specification, it is defined to be the following character sequence:

<ESC>%-12345X

3.1.2 ENTER

This command is implemented as defined on page 4-4 of [HP-PJL]. The possible values to be taken by

the LANGUAGE parameter are:

•AUTO

•CALCOMP

•CALS1

•CALS2

•VDS

•VCGL

•C4

•CGM

•VRASTER

•HPGL2 {Alternately, HP-GL/2}

•HPGL7585 {

lternately, HPGL}

•PCL

•POSTSCRIPT

•TIFF6

Version 10.0

ccXES PJL Interface

•JPEG

•ASCII

•FLASH

•DOWNLOAD

•FILENET

The FLASH and DOWNLOAD values are special values used for upgrading printer firmware and

downloading rendering objects such as raster stamps and fonts, respectively. The objects supported by

the DOWNLOAD facility are detailed in the DOWNLOAD Language section

s in standard HP-PJL, the INFO CONFIG command can be used to query the printer for the list of

currently supported data formats. Note that the LANGUAGE parameter to the HP-PJL ENTER

command detailed above is distinct from the standard HP-PJL Environment variable LANG which is

used to set the user interface language to English, French, Italian, etc. Note also, that there is another

environment variable called PERSONALITY which can take on the same values as the LANGUAGE

parameter above.

As specified in the HP-PJL specification [HP96], the next byte following the line feed at the end of the

ENTER command must be the actual job data. In particular, no further HP-PJL commands can be

placed between this command and the specified data format’s job data.

3.1.3 COMMENT

The COMMENT command is implemented as defined on page 4-6 of [HP96]. In addition, custom

commands specific to AccXES functionality are implemented within a COMMENT command. See the

Comment Command section for details.

3.2 Job Se

aration Commands

3.2.1 JOB

This command is supported as defined on page 5-2 in [HP96].

ll parameters are supported: NAME,

START, PASSWORD, and END. The maximum length of a valid NAME parameter is 80 characters.

Longer names will be truncated. The START and END parameters may not be supported in all AccXES

implementations.

From the HP-PJL Reference Manual (10 Edition, Oct 1997), the following requirement is explicitly

re-stated here for clarity:

"JOB commands can be nested. For example, a spooling application can send a PJL job that uses the

JOB command to another spooler that encapsulates the spooled job with another JOB/EOJ command

pair. When this is done, note that the job name from the outer JOB command is cleared or overwritten

by the inner command."

3.2.2 EOJ

The EOJ command is supported as defined on page 5-7 of [HP96]. The maximum length of the NAME

parameter supported is 80 characters. Currently, while the NAME parameter is accepted, it is

effectively ignored.
