Printer's remorse

When upon looking at a (usually large) printed document, you regret printing it.

Joe had printer's remorse because he just printed a 100 page file in colour when he meant to print it in black and white.

Jill had printer's remorse because she just realised she printed the odd pages of a long document twice.

Bill had printer's remorse because he forgot to check the "multiply slides per page" option and thus resulted in 120 pages with one lecture slide each.
