Agenda
Agenda

  • UPnP v1 Printing and Imaging Use Cases

  • UPnP v1 Imaging Update – Where are we?

  • UPnP v1 Deficiencies

  • UPnP v2 Requirements

  • UPnP v2 Use Scenarios

  • Schedule for UPnP v2 Imaging

  • Next Steps


Discovery and Installation

Plug Printer/Scanner directly into any available network port

WiFi (802.11b)

New wireless devices enter network and have instant access to printer/scanner

Imaging devices are discovered and can immediately be used (no drivers installation or setup )

  • End User Benefits

    • No need to manually install or share printer on the network (no networking knowledge needed)

    • Automatically discover printer/scanner and no need to search for new imaging devices added to the network.

    • Ability to print and scan from an extended range of devices (Pocket PCs, Cell Phones, Web Tablets)

UPnP Network

Print subcommittee status upnp v1
Print Subcommittee Status - UPnP v1

  • Printer Service Specifications Approved

    • Printer:1 Device

    • PrintBasic:1 Service

  • Minimal Data Format – XHTML-Print

    • IEEE-ISTO PWG Proposed Standard document

      • XHTML-Print

    • Required Embedded Image Format

      • JPEG (JFIF) – PrintBasic

  • Sample Implementers

    • HP, Oak Technologies, Canon, Microsoft

  • Printer Specifications published as Approved Standards – July 2002


Scan subcommittee status upnp v1
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 – September 2002


Upnp version 1 deficiencies
UPnP Version 1 Deficiencies

  • Data types

    • Missing Arrays and complex structures

  • Action Extensibility

    • Need to be able to specify whether arguments are optional/required or whether it should just use device settings (defaults)

  • Service Inheritance

    • Data inheritance may work here

  • Eventing

    • SOAP-based eventing instead of GENA so that secured eventing could be supported

    • Event filtering and grouping at the device level


Imaging wc architecture requirements
Imaging WC Architecture Requirements

  • Utilize standard web services to develop a standard service for:

    • Eventing

    • Discovery - Scalability of discovery for enterprise support

    • Security

  • Ability to extend Actions/Operations

  • Simple way to designate “Default” values

    • Outside of the SCPD

    • Run-time parsing of the SCPD is too much of a burden


Use scenarios printer for v2
Use Scenarios (Printer) for v2

  • 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”

  • Secure Printing


Use scenarios scan for v2
Use Scenarios (Scan) for v2

  • 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


Upnp v2 imaging schedule
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 – tbd

  • Complete Prototypes

  • PlugFests (minimum of 2) – tbd

    • Possible Hosts: Lexmark, Oak Tech., MS, HP

  • Incorporate feedback from Plugfests

  • Technical review, forum review, SC review

  • “Approved” specification - tbd


Next steps
Next Steps

  • Forward progress required on the UPnP v2 architecture
