Printing a whole report for one typo seems like a huge waste of paper and time. Most software has review modes that mimic a printed page anyway. Maybe the real issue is that the digital review process at that company is broken. A 12k error sounds bad, but was it actually a loss or just a formatting thing? Context matters a lot here.
You're totally right about the waste. My own printer has basically become a very expensive paperweight for catching my own dumb mistakes (like that time I spelled "client" as "clinet" on a cover sheet, real professional). A good review mode should catch most things, but some brains are just wired to see errors on physical paper. Still, a 12k mistake sounds like a process problem, not a paper problem. Gotta wonder what actually went wrong there.
