I have literally hundreds of HP print heads from a project, many partly blocked or burned out (they burn if you send them the wrong signals, and like 10% of the time I hit 'break' on my debugger it burns a few jets out if they're firing at the time), and had a coffee sitting right next to my desk so thought "why not".

This is incredible - you should write a blog about it. I want to see what that printout looks like!

When the main project is done, there'll be a blog post and the coffee test will make an appearance!

I'm also super curious what one might get up to with that many print heads, so maybe there's two posts in there!

yeah, but can you bubble jet maybe a photo onto a flat white?

That is a stretch goal of my project, but right now I wouldn't be confident I have a method to flush out the OEM and probably toxic ink.
