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

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)

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
![Page 20: Copyright © 2009, Printer Working Group. All rights reserved. 1 ISTO Printer Working Group Standards in Imaging and Manageability Lee Farrell Chairman](https://reader035.vdocuments.mx/reader035/viewer/2022062511/5514e6f855034693478b5a48/html5/thumbnails/20.jpg)

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
