I have just put a new document on the pwg site.
The document is an update of the document that shows what values
Set-Printer-Attributes takes for each IPP attribute.
The update discusses a new operation Get-Reset-Printer-Attributes which is
like Get-Printer-Attributes but returns the value that the attributes have
after a Reset operation. The values the Set-Printer-Attributes takes for
xxx-supported attributes are the values of xxx-supported returned from
Get-Reset-Printer-Attributes.
The URL for the document is:
