Actually, when printing, you want to set the glyphs at the spacing
for linear metrics. If device resolution matters, then you aren't
going to get WYSIWYG.

And the difference between linear metrics and printer-resolution 
device metrics is not important.

Yes, printers are a lot easier than screens in this aspect. The hard
part is showing something on the screen that has the same line breaks
as the printed output, but still looks good.
