Abstract

A printing apparatus includes a first processor which is connected to a first memory and converts print data into an image data format based on a page description language, a second processor which is connected to a second memory and performs image processing for print data of the image data format to generate data of a format interpretable by a printing unit, and a communication control unit which externally receives print data and transfers the received print data to either the first memory or second memory based on a descriptor. The second processor determines the format of received print data. When the print data has the page description language format, the first memory is set as the transfer destination in the descriptor. When the print data has the image data format, the second memory is set as the transfer destination in the descriptor.
