I have had some success using the Microsoft Photoed.exe program that used to ship with Windows until mid-way through the XP era, when it was replaced by the less versatile picture & fax viewer. Photoed has options such as Edge that produce outlines, the ability to select monochrome, posterisation to select the number of brightness levels, including just pure black and white I think it's available on the web, but following a suggestion on a "Bring back Photoed" forum some years ago, I simply copied the contents of the photoed folder from my old Windows 98 PC onto a USB drive and click the .exe file to run it.

I use the edge function to produce line representations of the perimeters of the tracks of printed circuit boards from digital.photos when fault-finding. This produces prints with black lines on a white background, allowing the tracks to be lightly coloured in by pencil and annotated with components and their values.
