Smith,

The definition of the filtering/coloring used has always been a little squishy, but generally Get-Printer-Attributes with a document-format should always return a proper subset of the Get-Printer-Attributes response without a document-format value supplied (where that proper subset might be the whole shebang...)

If that is not supposed to always be the case, then I worry that the term "filtering" might be misleading.  I cannot think of concrete examples for or against, but I wanted to point this out.

But when one of my colleagues actually went looking for the term being used in 2911 she couldn't find it.  And then I went digging...
