The fuzzy document layout seems overly complicated for something that I
don't think is very important for many end users. The reason I say that
is that if you care about exact scale (exact color?) you tend to be
aware of the paper size and printer limitations. The other case is where
you get this form for a strange paper size and you just want to make
sure that everything ends up on paper somehow.

Based on the above, I would think that a model that should work fairly
well is that the application makes some generic assumptions about the
output device based on the user's paper selection in the application.
Then when the user starts printing and has selected a printer, the
application should be able to tell when the selected printer is not able
to support the assumptions made. (E.g. selected margins not supported by
the printer) The application can then point out the problem and suggest
the user some corrective actions (e.g. scale to fit page/margins, let
user select different paper/margins in application, print as-is anyway,

Wouldn't that be a lot easier?
