1. A method for error checking raster objects including pixel information for a print job, wherein a plurality of raster objects form the print job, comprising:

  • receiving a raster object including sequence information indicating an ordering of the raster object with respect to other raster objects in the print job;

    determining from the sequence information for the received raster object and a previously received object whether the received raster object is received in a correct order with respect to other raster objects in the print job, to ensure that the pixel information for the raster object is intended for a current pixel line being processed; and

    indicating an error status if the sequence information indicates that the raster object was not received in the correct order with respect to the other raster objects in the print job.
