Ricoh SP 200 Linux CUPS Driver: reconstructing the printer's USB print protocol

Ricoh SP 200 Linux CUPS Driver reconstructs the printer's USB print exchange from captures of its Windows driver. Its notes identify PJL commands around JBIG1 raster data, document page transitions and image chunking, and accompany a C filter that converts CUPS raster input into the observed job format.
