Nice summary of all the different models, Scott.
I might add that the quality problems with the ImageWriter LQ 24 pin printer were addressed with a "rework" programme in which quite a number of the internal printer components were replaced. Among other issues, it reduced the noise produced by the printer. In my first job, I installed quite a few of the rework kits in these printers. Apple supplied a really natty little hook tool with each kit to install and remove all the springs in the printer. I still have a couple in my toolkit - they're very useful.
I always found it amusing that the Imagewriter LQ used an 80186 processor. Apple considered the Intel x86 processors as suitable for use in printers!
I'm not sure about the ImageWriter I and ImageWriter LQ, but the ImageWriter II was based on a C-Itoh printer mechanism, something that might be useful for tracking down parts.
