ABSTRACT:
A serial printer having print data processing unit. Print data for one line printing are successively stored in a line buffer. A size of a remaining data storing region is previously set, and the difference between the entire print data numbers for entire one line printing and the received print data numbers is measured. If the difference is equal to or smaller than the size of the remaining data storing region, a transfer commanding portion transmits a command signal to a transfer mechanism, so that operation of the transfer mechanism can be started. During the operation of the transfer mechanism, unstored print data are continuously stored in the line buffer. If all print data have been stored in the line buffer and if the carriage reaches a printing region, printing operation by a print head is started.
