The Printer Working Group maintains an open standards development environment and welcomes the participation of all who are interested in printing and imaging technologies, standards, and solutions. All that is required to participate is to be polite and agree to abide by the terms of the PWG Policy on Intellectual Property and Confidentiality, which roughly amounts to "anything you share in a PWG meeting, on the PWG FTP server, or on the PWG mailing lists can be included in a PWG standard or informational document."
You can participate in person or virtually via phone and/or email. Join the PWG mailing lists to ask questions, contribute, or learn when the next meeting is scheduled for a particular workgroup. You do not need to be a member to subscribe to a PWG mailing list. All members and interested parties are strongly encouraged to join the "pwg-announce" mailing list to receive notification of upcoming PWG Face to Face meetings.
New work starts with a white paper:
Extensions and new work for an existing workgroup can be proposed on the corresponding mailing list and discussed during a conference call or face-to-face meeting. New work outside the scope of an existing workgroup can be brought to the attention of the PWG Chair, who can direct you to an existing workgroup or schedule a "Birds of a Feather" (BOF) session at a PWG face-to-face meeting to discuss your proposal.
Many PWG standards offer a registry for attributes (aka elements and properties), operations, and values that third parties define for their particular usage. Send such registrations to the corresponding workgroup mailing list.
