Patent ID: 8373890

Claim:
A printing processing apparatus, comprising: an analyzing unit that analyzes components of print data of a first resolution, which is received from a host computer; a first raster processing unit that performs raster processing at the first resolution for the print data if a high resolution barcode is not present within the print data, and that performs raster processing at the first resolution for print data of a portion of the components of the print data other than a first optically read print portion if the high resolution barcode is present within the print data; a selector switch that outputs the print data to a first printing unit if a high resolution barcode is not present within the print data or outputs the print data to a second printing unit, of which resolution is higher than the first printing unit, if the high resolution barcode is present within the print data; a resolution conversion unit that converts the print data that has been processed by the first raster processing unit into the second resolution if the high resolution barcode is present within the print data, the second resolution being higher than the first resolution; a second raster processing unit that performs raster processing at the second resolution for print data of the first optically read printing portion of the components of the print data if the high resolution barcode is present within the print data; and a synthesizing unit that synthesizes the print data that has been converted into the second resolution by the resolution conversion unit and the print data that has been processed by the second raster processing unit if the high resolution barcode is present within the print data.
