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 Copyright © 2009, Printer Working Group. All rights reserved. 10

Some PWG Candidate Standards • • Common Semantic Model Print Services Interface IPP Fax Media Standardized Names XHTLM-Print, CSS-Print (migrated to W 3 C) PDF/is (developed in conjunction with Adobe) Port Monitor MIB (developed in conjunction with Microsoft) • Web-based Imaging Management Service • Imaging System Counter MIB Copyright © 2009, Printer Working Group. All rights reserved. 11

Current Working Groups • • Imaging Device Security (IDS) Internet Printing Protocol (IPP) Multifunction Device (MFD) Workgroup for Imaging Management Solutions (WIMS) Copyright © 2009, Printer Working Group. All rights reserved. 12

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) Copyright © 2009, Printer Working Group. All rights reserved. 13

Internet Printing Protocol (IPP) • IPP Job and Printer Operations Set 2 (JPS 2) • 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 Copyright © 2009, Printer Working Group. All rights reserved. 14

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 Copyright © 2009, Printer Working Group. All rights reserved. 15

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 Copyright © 2009, Printer Working Group. All rights reserved. 16

Common interest with SC 28 • Office Equipment Standards development • Printers • Multifunction devices • Imaging Services • ISO 10175 Document Printing Application (DPA) is the basis of our work Copyright © 2009, Printer Working Group. All rights reserved. 19

Benefits to SC 28 • 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 • • CIP 4 Job Definition Format Bluetooth Print Profiles UPn. P Enhanced Print Linux Foundation Open Printing Job Ticket API • PWG can readily provide significant imaging system expertise on work activity within SC 28 • Opportunity of considering PWG body of work for adoption as SC 28 standards Copyright © 2009, Printer Working Group. All rights reserved. 20

Summary Liaison status for PWG would create an opportunity to develop a more synergistic relationship with JTC 1/SC 28 … to the benefit of imaging systems and office equipment standardization Copyright © 2009, Printer Working Group. All rights reserved. 21
