II GS Printing

If you are referring to an Apple IIgs, I don't recall the IIgs having drivers for any Stylewriter, except perhaps the very first b/w Stylewriters. There was a third-party product called Harmonie that provided additional printer drivers, but I don't remember if it included drivers for the later Stylewriters.

Have you tried networking to a Mac and then printing from there?

Information about Harmonie is here(provided by Kenichi Watanabe):

Only Stylewriter I is mentioned(and ImagewriterII,LQ,and pointless).
Connecting to a Mac with LocalTalk is possible(transport of files).

As the ColorStylewriter 4100 has a LocalTalk port you may try this:
"Apple IIGS: Printing to the LaserWriter from AppleWorks
http://docs.info.apple.com/article.html?artnum=2098
The following instructions are valid for AppleWorks versions 1.3 and 2.0;
earlier versions of AppleWorks have not been tested with these
modifications. These changes support both the LaserWriter and the LaserWriter Plus."

Found an article describing the whole procedure you mention-but URL isn't working(got it as copy):
