I am trying to obtain fully functional color printing capability
with an old Apple Imagewriter II printer connected to a modern
Windows 95 PC.  By searching extensively, I have a driver which,
when installed, does an excellent job printing in black and white.
This driver makes use of the "universal printer driver" unidrv.dll,
and also another library program, dmcolor.dll.

The public-domain Imagewriter driver came with earlier (vintage
Windows 3.1) versions of unidrv.dll and dmcolor.dll, but I have been
running with the Windows 95 versions (the Windows 95 version of
unidrv.dll gives more functionality in setting options, etc.).

When I try to print in color, the result is poor.  The combination of
driver + printer will not print all colors.  It seems that the driver
is telling the printer to print all blue content as yellow or orange.

I have technical documentation for the Imagewriter II, and know all
the control and escape sequences that control its printing, including
the different colors.

My question is the following.  It would seem that a "universal printer
driver" would allow one to somehow customize a printer driver, using the
type of printer technical detail I have.  Is there a way to do this?
I'm thinking of something like constructing a table of printer control
codes and utilizing some sort of compilation procedure to produce a
customized driver from that.  Is this possible?  Are there any existing
techniques for doing this?

Please send any leads to "a.e.eckberg@worldnet.att.net".  Thanks!!!
