Some printers do not have full support for open printing langauges, and are only available with closed source Windows drivers. These printers, effectively, only run under Windows, hence the name. Similar to WinModems.
It may be difficult to identify WinPrinters simply from the packaging or sales bumf. A bad sign is the appearance of the acronym "GDI". Some that have been encountered in the wild are:
- NEC Superscript 610 (aka Silentwriter)
- Xerox M-series colour inkjets
