1. A system comprising:
an interface configured to receive rasterized print data;
a memory configured to store the rasterized print data; and
a print controller configured to compress each scanline of the rasterized print data by culling a region of leading whitespace, culling a region of trailing whitespace, compressing a data region disposed between the leading whitespace and the trailing whitespace, and inserting a tag having whitespace offset information for the data region within the scanline.
