OpenPrinting Summit/PWG Meeting Cupertino 2015

Actionable next steps toward the goal of making printing on Linux “just work”.

The printing activities of the Linux Foundation revolve around a few focal points:

  • For printer manufacturers, we want to make it easier to get their devices working, both by supporting driverless printing technologies and by helping them to produce drivers that work across distributions and to get those drivers in the hands of end users, to reduce problems that result from running unsuitable or outdated drivers or from need of drivers at all.
  • For application developers, we want to provide better facilities than we have today to add printing to applications in a portable and consistent way and so that the user gets full access to the printer's and the printing system's facilities and reliable results.
  • For operating system vendors (mobile, desktop, server, …), we want to put together a shared repository of printer drivers, so the OS/distribution vendors can share the burden of maintaining the (largely common) driver database with each other, but also work on ways of driverless printing to reduce the need of large driver collections. We also want to assure that all parts of the printing stack (spooler, renderer, driver, filters, …) work consistently and reliably together.

A major theme of the OpenPrinting Summit is ensuring that we have the proper standards in place at both the application and driver level to accomplish the goal of making printing on Linux “just work”. In addition, we will discuss related topics, such as developer tools, developer documentation, and testing, that will be important to the goal of making the standard actionable.

Also general development of the printing infrastructure, like Color Management, automatic driver download, driverless printing, mobile printing, cloud printing, PDF workflow, Ghostscript, XPDF/Poppler, … will be discussed.


We are inviting the most important people on the area of printing with Linux and free software, like developers of printing infrastructure (CUPS, Ghostscript, Poppler, Color Management, OpenUsability, …), printer drivers (Gutenprint, …), representatives of printer manufacturers (Ricoh, HP, Epson, Lexmark, Canon, Samsung, …), distribution vendors (Red Hat, SUSE, Ubuntu, …), and more.

We also offer a call-in service for all sessions and so people who are not able to come can still participate.

The OpenPrinting Summit will be held on Apeil 28 - May 1, 2015 (Tue-Fri), together with a PWG (Printing Working Group) meeting in Sunnyvale, CA, so the topics are from both PWG and OpenPrinting and as well the participants.

Either in person or phone-in participants should answer the survey on the PWG summit page under the second header.

These are the attendees who confirmed and/or registered up to now for participating personally (names in no special order, if not otherwise stated they are present on all four days):

  1. Michael Sweet (Apple, CUPS, PWG)
  2. Till Kamppeter (Canonical, OpenPrinting)

This is the list of attendees who will probably call in (names in no special order, note that these attendees will perhaps only call in for selected sessions):

  1. Hin-Tak Leung (author of several printer drivers, and contributor to other print-related software components)


The OpenPrinting Summit and the PWG meeting will be a joint event from Tue, April 28 to Fri, May 1 and will take place at Apple in Sunnyvale, CA.

See the PWG summit page for links to the slides and for latest changes.

Not all coffee breaks are explicitly listed.

Event Logistics

As the OpenPrinting Summit is held together with the PWG Meeting see also there for more detailed information.


Tuesday-Friday, April 28 - May 1


The OpenPrinting Summit takes place together with the PWG Meeting at Apple in Sunnyvale. We will be in the “Mountain Winery” room in the Mathilda 1 building located at:

250 S. Mathilda Ave.
Sunnyvale, CA 95014

See the PWG summit page for a map of the location.

Mailing List

For any questions or discussion about the contents or the Logistics of this event please use our mailing list. Please subscribe to the list if you are interested in the OpenPrinting Summit and/or want to attend it.

Everything important for attendees will only be announced on the list and summarized on this Wiki page, so please subscribe or stay subscribed if you like to attend.

Preparation conference calls

There will not be dedicated preparation phone meetings, but on the next two monthly OpenPrinting phone meetings the Summit will be central part of the agenda. They will be on Tuesdays, in the morning in the US and in the afternoon in Europe (always at 10am in San Francisco).


  • Tue, March 10: 10am San Francisco, 1pm New York, 6pm Berlin (5pm UTC)
  • Tue, April 7: 10am San Francisco, 1pm New York, 7pm Berlin (5pm UTC)

Dial-in number: +1-619-326-2730
Access code: 491659#

Additional phone meetings can be scheduled if needed.


To participate by phone there are different call-in numbers, see below.


Please respond to the PWG April 2015 face-to-face meeting survey whether you are planning to attend the meeting in person, by phone, or not at all. This will help us plan for services and make any necessary reservations.

Registration for the OpenPrinting Summit and PWG Meeting is free of charge.

Participation by calling in

We set up a conference phone in the room of the OpenPrinting Summit so that if you are not able to attend the Summit you can participate by calling in.

Most probably the following numbers will be used (numbers from last year), please re-check before dialling in as the numbers are subject to change:

Call-in toll-free number (US/Canada): +1 866 469-3239
Call-in toll number (US/Canada): +1 650 429-3300
Call-in toll number (US/Canada): +1 408 856-9570

We will give you the access code on request.

You can download the presentation slides via the links in the schedules on the PWG site before each presentation starts to see the slides when you participate by phone.


How well the call-in participation works depends very much on the room acoustics and the quality of the equipment on the conference site. Especially in big rooms there are often problems. At Apple we had always a good experiance with equipment and acoustics.


Will be announced, see also the PWG meeting page.

Sponsorship Opportunities

The preferred form of sponsoring the OpenPrinting Summit is overtaking the expenses for travel, accomodation, and meals for one or more of the participants who do not get their costs reimbursed by their employers, as they work on printing with free software in their spare time, independent of their jobs.

Note also that getting member of the Linux Foundation or donating to the OpenPrinting work group at the Linux Foundation can raise money for sponsoring the Summit, too.

If you want to sponsor, we can supply you with a list of sponsorship requests.

Please contact the organization team (see below).
