Printed Goofs are errors that appear in printed material, such as books, magazines, newspapers, and other publications. The two most common types of Printed Goofs are TYPOS and ERRATA. TYPOS are mistakes made when typing or writing, such as spelling errors or incorrect punctuation. ERRATA are errors that occur during the printing process, such as incorrect page numbers or incorrect text. Both TYPOS and ERRATA can lead to confusion and misunderstanding of the printed material.
