OpenPrinting Summit San Francisco 2009

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 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and to get those drivers in the hands of end users, to reduce problems that result from running unsuitable or outdated drivers.
  • 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, 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. 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, PDF workflow, Ghostscript, XPDF/Poppler, … will be discussed.

Summary and Results

Ira McDonald has written up a Summary.

Event Logistics

As the OpenPrinting Summit is held together with the Linux Foundation Collaboration Summit. See there for more detailed information.



Wednesday-Friday, April 8-10


The OpenPrinting Summit takes place together with the Linux Foundation Collaboration Summit in San Francisco at the same location, the Hotel Kabuki.

We will have one room for 30-40 people through all three days for the OpenPrinting Summit, so that it takes place in parallel to the Linux Foundation Collaboration Summit. We will have joint meetings of between 1 or 2 hours each with the LSB, Driver Backports, and Desktop Architects workgroups. We will perhaps also get 1 or 2 breakout rooms for 10-15 people which will allow us to split the group for some more specialized sessions.

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 be 4 preparation conference calls for the event. They will be on Tuesdays, in the morning in the US and in the afternoon in Europe.


Dial-in number: +1-218-936-7999
Access code: 491659#

If not otherwise stated the same dial-in number and access code will be used for all preparation conference calls and also for dialing into the Printing Summit itself (see below).


The OpenPrinting Summit is held together with the Linux Foundation Collaboration Summit. Therefore we use the same registration form for both events.

If you want to attend sessions of both events, please register only once through this registrstion page.

NOTE: Very important is to mention “OpenPrinting Summit” under “Why would you like to attend the summit?” and/or “OpenPrinting” under “If yes, which workgroups?”. Then your registration will get directly forwarded to the organizers of the OpenPrinting Summit. Otherwise it would be treated only be the organizers of the LF Collaboration Summit and they could reject your participation.

To the registration page

Please register early, as the number of participants is limited.

Participation by calling in

We set up conference phones at the event location so that if you are not able to attend the Summit you can participate by calling in.

We will use the same phone number and access code as for the preparation conference calls:

  • OpenPrinting Summit main room (Kyoto)
  • Dial-in number: +1-218-936-7999
  • Access code: 491659#
  • Breakout room #1 (Spring B)
  • Dial-in number: +1-218-936-7999
  • Access code: 495338#
  • Breakout room #2 (Spring C)
  • Dial-in number: +1-218-936-7999
  • Access code: 646797#

Please look for postings on the mailing list or for information in the schedules above for changes in the assignment of the rooms and the phone numbers.

NOTE: 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.


We will have negotiated room rates in the hotel where the event take place, the Hotel Kabuki ($159/night for King or Double Rooms, book online) and also in the partner hotel Hotel Tomo ($129/night for King or Double Rooms. book online). When contacting either of these hotels to make your reservation, please ask for the Linux Foundation group rate. Deadline for this rate is March 5, 2009, but note that the room blocks can get booked out earlier.

More details here, on the “HOTEL AND TRAVEL” tab.

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.

The Linux Foundation will also sponsor some participants, but we will probably get more requests for sponsorships. 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).
