As someone who doesn't do much with images anymore you should take my
advice cautiously. However the PBM file format is a simple way
to represent black/white images one bit per pixel. The only way
to get grayscale with PBM is by varying the density of black and white
points.
Look at the dithering options in convert for possible assistance. However
dithering does point density manipulation and lines are a problem I've not
worked with.

Hi folks --
I have a client who wants software to convert photo images into a form
that can be laser-engraved into metal or wood. I suppose this will
involve edge detection, and/or a way to translate the gray scale into
patterns of lines that give the impression of varying shades. The
client has specified that the resulting files must be 1 bit per
pixel. Can IM & MagickWand do this? Does anyone have recommendations
on what sort of operations to use?
Thanks --
