But it is *only* exported files that have the problem, and *only* on the
Lexmark. They print fine from other apps (including picasa) so I agree
that Word is probably involved in some way. But Word versions 15 years
apart behave the same way.

But they behave fine with picasa files that havn't been compressed by
Picasa export. So I think there is something wrong in the file header
which either the Word print engine or the Lexmark is getting confused about.
And the fact that just importing the file into Paint and saving it again
clears the fault points to something in the JPEG.

I don't know how to.
