AFAIK the current stance is that Poppler shifts this burden to the
viewer. For example conversion to PostScript is always possible but
whether the viewer allows the user to send the output to the spooling
service does not seem to be implemented within Poppler?

Since this just extends Poppler's existing methods used to store
documents, I think this cannot be used with the document being
successfully unlocked beforehand. (One could certainly call the methods
using this parameter but the result would be GIGO as I understand it.)

Best regards, Adam.
