A printer host comprising a list-forming unit for forming a band-corresponded drawing command list showing correspondence of respective drawing commands to a band or bands referring to a spool file stored in a hard disk device; a drawing command storage control unit which successively reads out the drawing commands corresponding to the respective bands from the spool file stored in the hard disk device according to the band-corresponded drawing command list, and stores the drawing command of one band that is read out in the drawing command memory; and an image data expanding unit which converts the drawing command of one band stored in the drawing command memory into image data and expands the image data in the band memory. This constitution makes it possible to decrease the number of drawing commands stored in the memory in the host. <IMAGE> |
