  2. Agenda • UPnP v1 Imaging Update – Where are we? • UPnP v1 Deficiencies • UPnP v2 Requirements • UPnP v2 Use Scenarios • Why Web Services? • Schedule for UPnP v2 Imaging • Future Meetings

  3. Scan Subcommittee Status – UPnP V1 • Scanner Service Definitions Complete • Scanner Device • Scanner Service • ExternalActivity Service • Feeder Service • Minimal Data Format – XHTML-Print • Required Image Format • JPEG (JFIF) Support • Sample Implementers: Canon, Ricoh, HP • Scanner Specifications published as Approved Standards

  4. Print Subcommittee Status - UPnP v1 • Printer Service Specifications Approved • Printer:1 Device • PrintBasic:1 Service • Optional Printer Service • PrintEnhancedLayout:80 shelved for now • Targeted at Photo Printing • Minimal Data Format – XHTML-Print • Planned PWG submittal of XHTML-Print • Required Embedded Image Format • JPEG (JFIF) – PrintBasic • Sample Implementers • HP, Oak Technologies, Canon

  5. UPnP Version 1 Deficiencies • Data types • Missing arrays and structures • Action Extensibility • Need to be able to specify whether arguments are optional/required or whether it should just use device settings (defaults) • Security – e.g., Access control • Service Inheritance • Data inheritance may work here • Eventing • Prefer SOAP-based eventing instead of GENA • Event filtering and grouping at the device level

  6. Imaging WC Architecture Requirements • Utilize existing toolsets – generic web services • Utilize standard web services to develop a standard service for: • Eventing • Security • AllowedValueList • Vendors must be able to extend and subset the AllowedValueList for Printer and Job attributes • Ability to extend Actions/Operations • Wild carding on the M-Search in SSDP • Scalability of discovery for enterprise support • Simple way to designate “Default” values

  7. Use Scenarios (Printer) • Location-based Printing – “print to the near-by printer” (hotel, home, airport, etc.) • Microsoft desktop printing for the mobile client • Driver-centric model using a PDL • PDA, cell phone (e.g., XHTML-Print) printing • Job Ticket Model + XHTML-Print • “Client operates the same—regardless of the location” • Print-by-URL (Printer http Gets file) • Secure Printing

  8. Use Scenarios (Scan) • Scan • Scan to a service (e.g., storage, application) • Scan to a fax • Scan to e-mail • Scan to Print (copy function) • Scan with user intervention

  9. Why Web Services? • Offloads printing functions: • Job control and workflow • Content rendering • Billing and accounting • Security and authentication • Uses latest standards in the industry (e.g., XML, SOAP, WSDL)

  10. UPnP v2 Imaging Schedule • Complete Use cases • Prioritize • Identify Requirements • Complete Device Model (MFD vs. Print & Scan) • Provide Architecture input • Complete Detailed service interfaces • Design Complete – March 2003 • Complete Prototypes • PlugFests (minimum of 2) – May, July 2003, • Possible Hosts: Lexmark, Oak Tech., MS, HP • Incorporate feedback from Plugfests • Technical review, forum review, SC review • “Approved” specification (Sept 2003)

  11. Next Steps • Future Meetings • Nov 4th – 7th – PWG in New Orleans • Nov 4th UPnP Print and Scan • January – Hawaii Meeting • Imaging Committee w/ 2 subcommittees: • Printing Subcommittee • Scanning Subcommittee

  12. For the interconnected lifestyle
