DeskJet500C prints color from Appleworks on IIgs?

[bla@hpcuhe.cup.hp.com (Brad Ahlf)]

I am posting for this for a friend.  I know very little about Apple II but
my friend is very knowledgeable.  I will repost my results if there is
interest.  Email to me at "bla@cup.hp.com".  Thanks.  My friend:

Has:
Apple IIgs with prodos 2.0.
Deskjet 500C.
Appleworks.

Is getting:
Driver for gs/os and additional gs/os program to run driver (?).
This is a generic(?) printer(?) driver program which downloads fonts(?).

**Wants**:
To use the DeskJet *color* capabilities with the Appleworks software.
It is OK to have only "simple" (e.g. RGYB) color capabilities and to have
to do "manual" tasks to make this work.

Guesses:
It is possible to "manually" use printer codes (escape codes?) in the
same way as using other fonts from within Appleworks (and printer
driver?) software to support simple color usage with the DJ500C.  If
so, needs the magic printer (escape?) codes for color output on DJ500C
and any additional hints on how to make this work.
