Well, if it looks fine in Illustrator (and Preview) I'm pretty
confident the PDF does not have whatever it is that the direct to-
printer. What I did notice only when I'd uploaded the images (made
much more obvious by the scanner's auto-sharpen) is that every fill is
offset a little to the lower left to the outlines ...

I did try eagle -> PDF -> some other app -> Print and ... the smear is
gone, although something else has happened to drill holes - I'm lucky
enough to have Illustrator, I think I'll be sticking to that route!

That would be nice, but it also etched just fine, my first flirtation
with 10mil traces and running things under SMD parts. Infuriatingly, i
managed to break a trace with the drill chuck ...
