Objectives of BBF / PWG Liaison for
CWMP Printer/MFD Data Model
• BBF / PWG collaboration on CWMP Printer Data Model
• Ensure management requirements input from BBF members
• Ensure technical and structural input from BBF experts
• Ensure best practices for CWMP data models with BBF experts
• PWG project to define CWMP Printer Data Model
•
•
•
•
•
•
Ensure wide visibility since all PWG working drafts are public
Ensure printing requirements input from PWG members
Ensure early engagement w/ OS, MPS, and printer vendors
Ensure fidelity via machine translation of PWG Semantic Model
Ensure usability via Thinxtream prototype activities
Facilitate rapid deployment by printer vendors
• BBF liaison to review CWMP Printer Data Model
• Ensure visibility via Thinxtream as joint BBF / PWG member
• Ensure quality via BBF review cycles before PWG Last Call

Why use PWG Semantic Model
as Basis of CWMP Printer/MFD?
• PWG SM is the core standard of the printing industry
•
•
•
•
Referenced by IETF, IEEE, W3C, DMTF, CIP4, and many others
PWG Semantic Model v1.0 (5105.1-2004) – print
PWG MFD Model v1.0 (5108.1-2011) – print, scan, fax, email
Abstract Model w/ XML Schema and WDSL/SOAP Bindings
• PWG SM is based on Internet Printing Protocol (IPP)
• IETF IPP/1.1 (RFC 2911, September 2000)
• Ubiquitous in network printers for over a decade

• Conformance profiles of 25 IETF and PWG extensions for IPP
• PWG IPP Everywhere (PWG 5100.14-2013)
• Mobile, driverless printing (laptops, tablets, cellphones)
• PWG SM is evolving with technology advances
• PWG IPP Shared Infrastructure – Cloud Print extensions
• PWG Semantic Model 2.0 – update of PWG MFD Model v1.0

Status of PWG CWMP Activities –
CWMP Printer Data Model (1 of 2)
• CWMP Printer Data Model Document
• Defines use cases, deployment scenarios,
requirements for complete lifecycle management
- device provisioning/configuration
- patches/upgrades for software/firmware/security
- meter reading/accounting
- diagnostics and status monitoring
- supply chain and OSS/BSS integration (NBI)
• Telecoms – provide new value-added services, raise
ARPUs, augment management of other IP based devices
• Managed Print Service providers – manage multiple
customer facilities across enterprise firewalls
• Enterprise IT staff – perform accounting/monitoring
• Print kiosks managed by Telecoms – services for mobile
phone subscribers – VAS either pre-paid or post-paid
services

Status of PWG CWMP Activities –
CWMP Printer Proxy Prototype
• Set of CWMP data elements are implemented in
CWMP Proxy for network printer – see next slide
• CWMP Proxy uses IPP, SNMP, and HTTP protocols
to gather data from the network printer
• CWMP Proxy could be in a printer’s firmware and
connect directly to the ACS over the Internet
• Prototype demonstrates that a local or remote
CWMP management application can get and set
CWMP Print Service properties from the ACS thru
the CWMP proxy to the network printer
