Problems of Linux Print Dialogs

Applications have their own print dialogsFor many applications, Print Dialog is an integrated part of the application.

Consistent User Experience--------------------------We want to define printing dialogs that are consistent in layout and print options offered to the user across all applications and desktop environments.

Print Dialog Extensibility--------------------------We want to design a platform neutral standard & API that allows operating system, application and printer vendors to extend the common printing dialog with their own extensions.

We want to intensively explore the idea of a "printing dialog provided as a desktop service" for use by applications and GUI toolkits to construct print dialogs or to query for printer configuration information.

Phase 1: Make Common Print Dialog a reality. Make it into Linux distributions THIS SUMMER.

•CPDAPI 1.0 specification•Make stand alone CPDAPI enabled Gtk+ print dialog module•Patch Gtk+ Tool kit to make CPDAPI invocation. •Patch Qt Tool kit to make CPDAPI invocation.•Put it into a Linux distribution

Phase 2: •Config utility for user to pick CPDAPI enabled Print dialog.•Open Usability Print Dialog

Challenges

Is CPDAPI specification provides enough flexibility so it can be used to replace existing printing API? (Guten Print, Open Office, Lotus Notes, Scribus, etc)

Do we provide and document a clear mechanism if D-Bus is not installed/available, what application should do?

When a new CPD is installed, how to register it with D-Bus? When the CPD is removed, will D-Bus pick another CPD as default dialog?

Have application vendor’s concerns be addressed? (Default print setting for Document/User session, etc)

Do we need a print preview API, where does it fit in?
