Digital BW, The Print

Mark - I think it's largely a matter of preference, though I don't know that
printer and can't say if there would be any problems with feeding the
heavier weight paper.  I use an 1160, and cut a piece of foamcor to the size
of the sheet that I will be using and placed in the printer as though it was
a piece of paper.  That way the printer thinks that there is a stack of
paper, and will take the paper smoothly if you place a single sheet on top
of the foamcor.

I think you'll find the 188 fine for small prints but may want to try the
308 for anything large.
