Abstract

These is disclosed a printer which continues, after resumptio of power, printing which was in progress before a power failure. In this printer, the disconnection and resumption of power is detected by a detection circuit. When power is once disconnected and then restored, the presence of any character other than blanks which may have been printed by a printing head is detected in a line where the printing head is positioned. If any character other than blanks had been printed on the line where printing operation was interrupted due to disconnection of power, the printing head is controlled to print for crossing out the line after resumption of power. On the other hand, if nothing other than blanks had been printed in the line where the printing operation was interrupted, the printing head is controlled to print the same contents on the line as should have been printed on it without starting another line after resumption of power.
