Imaging Committee Chair

Hewlett Packard

  • 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
  • Forward progress required on the UPnP v2 architecture
