Drivers was the first think I looked at. I'm just printing a word file.
The print preview is fine. The lexmark output fails, other printers are OK.

That's what I am doing. I was using Picasa to do the resize because
that's what I use for cropping and straightening (and maybe occasionally
a tweak on fill, contrast, or colour). My point is that the resized
picasa file fails to print *to one specific printer* when put into the
word document. But if I import the file into paint and re-save it before
the insert then everything is fine.
