foo2qpdl is a printer driver for printers that use the QPDL wire protocol for their print data, such as the Samsung CLP-300, CLP-310, CLP-315 or the Samsung CLP-600, CLP-610nd, CLP-620nd. These printers are often erroneously referred to as winprinters or GDI printers. In fact, QPDL printers are raster printers which happen to use a very efficient wire protocol. QPDL is just one of many wire protocols that are in use today, such as PostScript, PCL, Epson, and ZjStream.
