I think you've already mentioned this before somewhere: How about a testing routine triggered by some M command. Then it wouldn't be necessary to include this with every print.

If you guys implement something like this I would volunteer to do a bullet-proof write-up on how to use this setting and what do learn/adjust from different outcomes for beginners.
