ABSTRACT:
A raster scanable number is representative of a number of raster scans that can be performed with dot image data stored in a print image buffer. A raster scanned number is representative of a number of raster scans actually performed by a print mechanism. The raster scanable number and the raster scanned number are compared to detect an occurrence of a print overrun. When the print overrun is detected, the data processing load imposed when compressed print data received from an external unit is decoded is calculated, and the storage capacity of the print image buffer is expanded to a degree determined according to the data processing load thus calculated. Therefore, even when the data processing load is large, such as during encoding processes, so that dot image data developing processes are delayed, the print image buffers will not be emptied of dot image data for printing and printer overrun can be prevented to a very high level.
