I'm finalizing the latest set of edits to IPP FaxOut and came upon this issue as I added the AddFaxOutHardcopyDocument operation: how does one tell the FaxOut service that the input document is duplexed?
The Copy service does this by putting InputSource and Sides into a CopyInput container group, but FaxOut does not have this construct.
Related issues: control over color/grayscale/bi-level scanning, resolution of scanned image data, and all of the other knobs at:
A few potential solutions:
1. Extend InputSource (input-source) to include duplex variants (adf-one-sided, adf-two-sided-long-edge, adf-two-sided-short-edge); this doesn't address any of the other input parameters.
2. Add a new InputSides element (input-sides) with the usual values of Sides, InputColorMode/Entry, InputResolution, etc.
3. Add FaxOutInput as a new container for all of the CopyInput ticket values, and deprecate InputSource as an operation element on its own. This would allow us to control the color mode, resolution, orientation, etc. of the faxed document and would better align FaxOut with Copy.
For IPP we would probably use a collection attribute called "input-attributes" which would contain the usual job template attribute names and values, just for the input side of things.
