摘要： Systems and methods are provided for handling print data. One embodiment is a system that includes an interface that receives rasterized print data, a memory that stores the rasterized print data; and a print controller that compresses 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.
