Driver for printers that use the ZjStream wire protocol

foo2zjs is an open source printer driver for printers that use the Zenographics ZjStream wire protocol for their print data, such as the Minolta/QMS magicolor 2300 DL or Konica Minolta magicolor 2430 DL. These printers are often erroneously referred to as winprinters or GDI printers.

However, Microsoft GDI only mandates the API between an application and the printer driver, not the protocol on the wire between the printer driver and the printer. In fact, ZjStream printers are raster printers which happen to use a very efficient wire protocol which was developed by Zenographics and licensed by most major printer manufacturers for at least some of their product lines.

ZjStream is just one of many wire protocols that are in use today, such as Postscript, PCL, Epson, etc.
