The Linux Foundation OpenPrinting work group, organises a get-together 24-27 September in Montreal.

As stated on their site, 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across distributions and to get those drivers in the hands of end users, to reduce problems that result from running outdated drivers.
• For application developers, we want to provide better facilities than we do today to add printing to applications in a portable and consistent way.
• 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.
• A major theme of the Printing Summit will be ensuring 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, certification, and testing, that will be important to the goal of making the standard actionable.
