Printing mistakes, such as ERRATA and TYPOS, are common errors that can occur when printing documents. ERRATA is a Latin term meaning 'mistakes' and refers to errors in printed material that have been overlooked during the editing process. TYPOS, on the other hand, are mistakes made while typing or entering data into a computer system. Both of these errors can lead to confusion and frustration for readers, so it is important to proofread documents carefully before printing them.
