I provided them to retain the symmetry with how the "paper" field is
managed; it has a "get" function which is currently called from
plugins/xml_sax/xml-sax-write.c .

For xls export we'd probably need do a linear search through
paper_size_table to find a matching entry (if any) using some kind of float
comparison with epsilon for gnome-print units. I haven't spent time on this
yet because, as you point out, the information we now import is lost in a
typical use scenario (load, print) before we even get to the point of
saving.

it may be easier (though less reliable) to try to preserve
the xls paper id number.

This seems doable.

This is something I haven't yet gotten a grip on. Back when the gnome-print
initialisation was done on startup, I tried to trace down where some
paper related information was lost, and it seemed there was some sort of dup
done of gnome-print information which destroyed part of the information in
its src.

I don't grok the interaction with gnome-print; I'd appreciate
pointers/advice here.
