ABSTRACT:
A printer control device capable of performing a buffer memory clearing operation within a short period of time without complicating the control of the clearing operation. A RAM 8 stores an end address of an immediately preceding block of print data. CPU 6 develops a present block of print data received from a host computer into a buffer memory 8a so as to overwrite it on the immediately preceding block of print data which has been stored in the buffer memory 8a. When an end address of the present block of print data developed into the buffer memory 8a is smaller than the end address stored in the RAM 8, storage locations of the buffer memory 8a from the end address of the present block of print data to the end address stored in the RAM 8 are cleared. Then, the end address stored in the RAM 8 is replaced with the end address of the present block of print data.
