I'm writing DCA(device companion application) for v4 printer driver using XAML and C#. I have added to drivers gpd file
line with constraints : "*InvalidCombination: LIST(Orientation.Landscape, ColorMode.Color)". Orientation
and ColorMode are default features maintained by desktop extension and default metro driver UI. After installing driver, when I print from desktop application this constraint works well, i.e. I can't send document for printing when Orientation.Landscape
and ColorMode.Color is selected and warning icon is shown for user. When I try to print from Metro application
I can select both features and send to printer without any notification.
Do you have plans for support user notification about incompatible printer options in default
metro driver UI (as in desktop extension now)? How to support such notification in DCA for other features?
