Abstract
Disclosed is a printer which drives a drive motor for a type wheel or a carriage therefor by a signal derived by processing a first digital signal resulting from a position error signal and a second digital signal which is delayed by a predetermined time period. The digital signals can be processed by an LSI chip which assures a highly reliable, low cost and compact printer.
