The Printer Working Group |
|---|
About the PWGThe Printer Working Group (or PWG) is a Program of the IEEE Industry Standards and Technology Organization (ISTO) with member organizations including printer and multi-function device manufacturers, print server developers, operating system providers and print management application developers. The group is chartered to make printers, multi-function devices, and the applications and operating systems supporting them work together better. |

Web-based Imaging Management Services (WIMS), This working group is concerned with the management of imaging services and devices via the Web. Although past work has included the definition of a web based protocol for this purpose, the major part of the activity has been and continues to be the definition of new and the recasting of previously defined management elements into a web management compatible context. That has included the generation of the Counter Specification and the realignment of the DMTF/CIM printer class with established printer management models. Work is continuing with the update and upgrade of the DMTF/CIM printing classes in anticipation of this forming the basis for print management over the Web.

Multifunction Device
Working Group (MFD),
The MFD working group is focusing on modeling of the MultiFunction
Device (Print, Copy, Scan and Fax). Standardization of MFD model and
semantics will support interoperability of devices and services in
local and enterprise networks enabling improved job submission, job
management and remote administration and support. The goal of the MFD
project is to define a unified semantic model and set of abstract
operations for the most common and essential service and device
features of the MultiFunction Device. MFD Wiki: Peter Zehler, Chairperson |

PWG
Semantic Model (SM) is a high level overview of the semantics
that have been defined by the PWG. The primary document describes the
semantic elements defined in various PWG documents and PWG documents
submitted to the IETF. The Semantic Model also incorporates additions
made by external groups addressing print systems. Every semantic
element in the document includes a reference to the document and
section that details the semantic definition. The specification also
contains a high level description of the Actions that operate on the
objects and attributes in the model. This document does not describe
the mapping of the semantics onto a specific protocol or network
environment. An XML Schema based on the Semantic Model document is
included. This project also includes the process to allow additions to
the Semantic Model specification and schema. PWG SM Wiki: Peter Zehler, Chairperson |

PWG MIB WG (PMP)
, The PWG working group has developed a number of
Management Information Base (MIB)standards for the management of
printers, finishing devices, and imaging jobs. The working group has
also recently completed a Port Monitor MIB that is now required by
Microsoft for network printers to operate with the Vista OS. Currently
the MIBs working group is developing a specification to allow a
multifunction device to use the existing printer alert table to report
problems within the non-printing hardware. The group also remains active to support any future MIB development efforts and to maintain the related IANA registrations. PWG MIB WG Wiki: (coming soon) Ron Bergman, Chairperson |

The
Internet Printing Protocol (IPP),
The IPP working group has developed a modern, full featured network
printing protocol which is now the industry standard. IPP allows a
print client to query a printer for its supported capabilities,
features, and parameters to allow the selection of an appropriate
printer for each print job. IPP also provides job information prior to,
during, and at the end of job processing.
The IPP working group remains active for the maintenance of IANA registrations and PWG/ISTO standards, and to support current and future work items. IPP Wiki: (coming soon) Ron Bergman, Chairperson |

Projector
and Display
Management (PDM), The
Projector & Display Management working group is developing a model
of the management information that is relevant to installed video
projectors and large-format displays. The working group will
first establish an SNMP MIB for the management of projectors and
displays, then consistent semantic guidelines for embedded web servers
and other management protocols, and a web services schema. Why manage projectors? If projectors and digital displays are to function as utilities in conference rooms, lecture halls, retail venues, sports stadiums, etc., they must work reliably. Just as printers always need paper and toner, projectors always need lamps, fans, air filters, the right zoom, the right focus, the right color settings, the right input connector, etc. The health and setup of such resources of installed projectors and displays need to be managed remotely.
