Abstract

A printing apparatus capable of high-speed printing with low costs. Upon printing on a recording sheet based on print data inputted from an external device, print-buffer allocation is controlled in such manner that existence/absence of print data with respect to a printing area of a recording sheet is examined by a unit of print buffer capacity, and if there is no print data for a printing area, no print buffer is allocated to printing by a print head in the printing area. This control is managed by a print buffer management table in which an ID number of an allocated print buffer and information indicative of a state no print buffer is allocated are stored.
