printer's error

Even if it’s not a printer’s error or a truncation, fat might not mean what we think it means.

Of course, no one would try to spend a $7.6 million coin, or mail a letter with one of those postage stamps made famous by a printer’s error.

In particular there was a tendency for characters to ask semi-rhetorical questions punctuated with a period instead of a question mark; this has not been changed since it may be a stylistic choice, not a printer's error.

This may possibly be a mere printer’s error.

For the record, The Phantom's creator intended for the character's outfit to be gray — Falk even considered calling him "The Grey Ghost" — but a printer's error resulted in the familiar, albeit impractical, purple suit.
