Abstract
A printer has a printing mechanism for printing on printing paper in accordance with data stored in a buffer memory which is divided into a non-overwrite memory region and an overwrite memory region. The data entered from an external device is first stored in the non-overwrite memory region of the buffer memory. If the data in the non-overwrite memory region exceeds the storage capacity during printing, the excess data is stored in the overwrite memory region. When the data stored in the overwrite memory region exceeds the storage capacity, the printer overwrites subsequent data entered from the external device onto the previous data stored therein. Moreover, during reprinting, the data in the non-overwrite memory region of the buffer memory is read to activate the printing mechanism.
