Software Drivers
These Apple printers were designed for use with Apple II and Macintosh computers, and contain many useful design features accessible only by those systems. Some of the printers have some similarity in design with printers that were designed, tested, and sold for PC users. Therefore, there is a remote possibility that PC drivers may control some of the functions on these printers. We have no knowledge which drivers may or may not work. If you wish to pursue this, some starting points:
Printer | PC Driver |
ImageWriter II | Epson FX or similar driver |
StyleWriter | Canon BJ-20 |
StyleWriter II | Canon BJ-200 (possibly also the BJ-200e) |
Color StyleWriter (early models) | Canon Color BJ-600 |
