In my opinion a shrink-to-fit has to be preferred, but configurable
options of shrink-to-fit, crop-to-fit, reflow-text, and prompt-user
should be given. Under no circumstance the text should be reflown if a
user simply loads a document, but has no printer offering the needed
paper size/imageable area. The user should be simply warned then, theat
graphical elements can get lost and he should be asked on the first
attempt to print.

Therefore always ask the user before doing that, as long as he does not
configure to not being asked.

In addition, text parts (chapaters, paragraphs, ...) could have "layout
hints", like protection against being reflown.

Yes, here layout hints would be useful, to lock the address into its place.

Yes, these are the two items which describe the printing media
numerically. Names (as in PageSize/PageRegion) can always be non-standard.
