From the description provided, here is the approach I would take. I'm not sure if I am understanding your process well enough.
I would create a parent table for the Instructions. Your child table (printer model) would have a link to parent field where the appropriate Instruction would be selected. The parent table could have multiple image fields to hold your pictures.

This is a great suggestion and good to have when I was at my last employer and supporting TrackVia.
There were a few instances where my tables were busting at the seams.
Hope to get back with a TrackVia client supporting the app.
