Standards in Imaging and Manageability

Lee FarrellChairman ISTO PWG


Who is the Printer Working Group?

• Companies interested in improving the market for imaging-related products

• Members understand that developing standards is a necessary part of achieving this goal

• Not just printer vendors: • Multi-function device manufacturers• Print server developers• Operating system providers• Print management application developers


PWG Members


PWG Goal

We are chartered to make

• printers• multi-function devices• applications and operating systems that support them

… work together better


Printer Working Group - History

• PWG name adopted in 1993• Early projects with IEEE and IETF

• IEEE 1284.x series of standards• providing status, configuration, communication and control

over IEEE 1284 parallel port

• Standard Printer MIB RFC-1759 (IETF)• based on ISO 10175 Document Printing Application (DPA)

• In 1999, organized under IEEE-ISTO• Industry Standards and Technology Organization• Affiliated with IEEE Standards Association• Formalized organizational procedures, processes


Affiliations and Liaisons

• Multiple activities achieved via collaboration with other organizations and standards groups • IETF - Printer MIBv2, Finisher MIB, Internet Printing

Protocol (IPP), IPP Extensions• W3C - XHTML-Print, CSS-Print Profile• CIP4 - Job Definition Format (JDF) • Bluetooth - Print Profile• DMTF - Printer Class, Printer Service Class


Affiliations and Liaisons

• Information exchange via PWG member overlap• Microsoft Web Services for Devices (WSD)• Trusted Computing Group• DMTF• Linux Foundation Open Printing• UPnP• IEEE P2600 Security


Work Structure

• Six face to face meetings per year• Plenary, Working Groups, BOFs

• Working Group teleconferences• Weekly or bi-weekly

• E-mail discussion

Proven Activity

• PWG has produced or been involved in many of the standards used by electronic printing industry

• Developed standards in the following areas:• Device management (Printer MIB, Finisher MIB etc.) • Hardware level interface (IEEE 1284)• Transport layer interface (IEEE 1394.3)• Datastream standards (XHTML-Print)• Application layer print/scan and management protocol

standards (IPP, PSI, etc.)• Standardized model of printer services

• consistent with ISO 10175 – DPA• used by virtually all current print protocols over multiple

interfaces and operating systems


Some PWG Candidate Standards

• Common Semantic Model• Print Services Interface• IPP Fax• Media Standardized Names• XHTLM-Print, CSS-Print (migrated to W3C)• PDF/is (developed in conjunction with Adobe)• Port Monitor MIB (developed in conjunction with

Microsoft)• Web-based Imaging Management Service• Imaging System Counter MIB


Current Working Groups

• Imaging Device Security (IDS)• Internet Printing Protocol (IPP)• Multifunction Device (MFD)• Workgroup for Imaging Management Solutions

(WIMS)


Imaging Device Security (IDS)

• Addressing the assessment of the “health” of devices before allowing them to access the network

• Defining a standard set of metrics that can be measured or assessed in Hardcopy Devices to gauge if they should be granted access to a network

• Defining example “bindings” for how these metrics are used in individual network assessment protocols• Microsoft Network Access Protocol (NAP)• IETF Network Endpoint Assessment (NEA)


Internet Printing Protocol (IPP)

• IPP Job and Printer Operations Set2 (JPS2)• Extends IPP Production Printing Set 1• Resubmit-Job, Cancel-Jobs, Cancel-My-Jobs, job save, proof

print, etc.

• IPP Version 2.0• Organizes optional features into compliance levels• First edition defines IPP/2.0 and IPP/2.1• Future edition will define IPP/2.2

• IPP Printer State Extensions (PSX)• IPP Printer/Finisher alerts

• “IPP Everywhere” Birds of a Feather kick-off in February• Cross-platform printing support for all IPP/2.0 printers• Print from any Client to any Printer, without vendor-supplied

printer drivers


Multifunction Device (MFD)

• Modeling of imaging services and subunits that comprise a network connected MFD

• Standard semantic definition for Subunits, Services, Jobs, Documents, Operations, etc.

• XML schema used for data modeling• Service elements include:

• Print • Scan • Resource • Copy• E-mail• Fax• Transform


Workgroup for Imaging Management Solutions (WIMS)

• Supporting the remote management of Hardcopy Imaging devices

• Mapping into standard management semantics and protocols, e.g., SNMP, DMTF/CIM, and Web Services Management

• Aligning DMTF/CIM classes with PWG MFD Model• Support and update of the printer-related MIB

documents• Printer MIB, Finisher MIB, Counter MIB

• Power Management MIB


List of Standards (1)

• IEEE 1284.1-1997: Transport Independent Printer/System Interface• protocol for returning printer configuration and status

• IEEE 1284.2: Standard for Test, Measurement and Conformance to IEEE 1284 (not approved)

• IEEE 1284.3-2000: Interface and Protocol Extensions to IEEE 1284-Compliant Peripherals and Host Adapters

• protocol to allow sharing of the parallel port by multiple peripherals (daisy chaining)

• IEEE 1284.4-2000: Data Delivery and Logical Channels for IEEE 1284 Interfaces

• protocol to allow a device to carry on multiple, concurrent exchanges of data• IETF Printer MIB v1, RFC 1759, March 1995

• based on ISO 10175• IETF Job Monitoring MIB, RFC 2707, November 1999

• based on ISO 10175• IETF Internet Printing Protocol v1.1, RFC 2910-2911, September 2000

• Encoding and Transport (RFC 2910)• Model and Semantics (RFC 2911)• based on ISO 10175

• IETF IPP URL Scheme, RFC 3510, April 2003• based on RFC 2911


List of Standards (2)

• PWG IPP Document Object, PWG 5100.5, October 2003• based on ISO 10175

• PWG Internet Printing Protocol v2.0, PWG 5100.10, July 2009• based on many IETF and PWG standards extending IPP/1.1


Common interest with SC28

• Office Equipment Standards development• Printers• Multifunction devices• Imaging Services

• ISO 10175 Document Printing Application (DPA) is the basis of our work


Benefits to SC28

• PWG has a strong heritage of developing imaging systems management and services standards

• Recognition within the industry• PWG standards are normatively referenced by several

other imaging system public standards• CIP4 Job Definition Format• Bluetooth Print Profiles• UPnP Enhanced Print • Linux Foundation Open Printing Job Ticket API

• PWG can readily provide significant imaging system expertise on work activity within SC28

• Opportunity of considering PWG body of work for adoption as SC28 standards


Summary

Liaison status for PWG would create an opportunity to develop a more synergistic relationship with JTC1/SC28

… to the benefit of imaging systemsand office equipment standardization
