Just a random thought, and if I wasn't asking the question myself I'd probably down vote it, but... are screenshots the best way to show printer settings, or would a text version be better?
Ok, yes, a screenshot is probably easier to do and post, and will show a familiar UI and be easy on the eye and make it easy to notice errors/improvements.
However, having a (standardised) text format would make it searchable. After all, other sites always say, "please copy and paste the error rather than post a screenshot" - because the text in a screenshot is not searchable.
Yes, it could/would be a pain to enforce this rule (is it possible to easily export printer settings as a file file?) and/or edit the text version of the settings into the post.
This is probably a daft "thought experiment" of an idea... but I thought I'd float it anyway.
