A misprint occurs, for example, when no foil stamping is included in the Topps logo, or if the back of a card is left blank. Basically, something happened in the printing process where a step was missed.

An error, on the other, hand is where something went wrong in the design process. Like calling Cal Ripken Jr. a pitcher, rather than SS. Sometimes a limited print run of such cards will go out before they are corrected in subsequent batches. Generally, very few of the error cards make it to market and, as a result, they are rare (compared to the corrected version).
