If the mistake happened in the typesetting stage, printed books could spread errors much more efficiently, as in the infamous "wicked bible" of 1631, where a typesetting error made the ten commandments contain the amusing phrase "Thou shalt commit adultery". Surviving copies are quite the collectors' item as most were destroyed.
Usually, though, errors are corrected and every every printing has fewer errors than the previous one.
