The embedding layer needs a printing API. This should separate the UI from the printing so that the embedder can their show own print dialog and pass print parameters to the print method for the actual printing. There should be a feedback/abort printing interface.

CC'ing Don. Don, do you have any suggestions on how I can implement this interface?

Requirements for embedders & printing. Embedders must be able to: 1. Implement their own print dialog or use the default one 2. Query the list of available printers 3. Query the print parameters for each printer 4. Print using a target device & parameters specified by the embedder 5. Print all the document, a page range or selection range 6. Receive print progress notifications via a callback and the ability to abort 7. Print frames as a single document or as separate documents 8. Print preview (via a stylesheet?)

Printing currently has one call that can be made. The biggest problem about defining API's for printing is that some of the information (like print range) are contained in the native dialogs for some platforms and not in others. The way we solved this problem is we defined a printer settings object.. some of the information might be duplicated..but this cross platform object can define parameters on a xplatform or a single platform way. A good example of this was how we were going to to Portrait vs Landscape, which are implemented differntly on different platforms. I think the way we can do the API's are to use this object print setting object.. which will be set by the embedding application.. then in the layout engine it can use the settings in this object. There is a silent parameter on the print API... so if the embedding application whats to handle the native dialog for itself.. this parameter can be set to silence the layout engine putting up the dialog. Does this make sense.. you want to talk on the phone to discuss this some more.. Don

Updating QA Contact

*** Bug 42843 has been marked as a duplicate of this bug. ***

Checked in the IDL files.. for the nsIBrowserPrint and nsIPrintSettings...

Moving to mozilla0.9.1

updated my keywords

Moving general printing API work to future. Specific methods and interfaces for the printing API required for bug 70946, bug 70949, bug 70950 have specific milestones which are either marked mozilla0.9 or mozilla0.9.1

Correction: Changing QA contact for the Embed API bugs to David Epstein.

Reassigning to Rod since he is working on the printing API's.

changed qa contact to Dharma.

We have covered most all these items except item #3. Which at the time there isn't a requirement for that specific thing. I am marking this "fixed" and if item #3 is a "must do" then open a new and separate bug with an explanation where we are currently lacking functionality.
