Other forms: misprints; misprinted; misprinting
An error in a published text is a misprint. If a newspaper headline reads "Local Sailing Team Wins International Goat Race," that's probably a misprint. At least we hope it is!
A mistake in anything that's printed is a misprint. You might also call it a typographical error or typo. Misprints are an embarrassment for the publisher, since they're evidence of a hasty printing job or a lack of careful proofreading. Spelling and grammatical errors (using then instead of than, for example) in books, magazines, or newspapers are common kinds of misprints.
