    Finally, configure the serial port of the computer to match the printer configurations as above and assign the port to LPT1 by running this autoexec program:

    mode COM1:96,N,8,1,P
    mode LPT1:=com1

    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
