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

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

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 PDLDriver-centric model using a PDL PDA, cell phone (e.g., XHTML-Print) printing
Job Ticket Model + XHTML-Print Job Ticket Model + XHTML-Print “Client operates the same—regardless of the
location”
Print-by-URL (Printer http Gets file)
Secure Printing

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

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)
