You'd need to provide Filter lines for application/vnd.cups-postscript
and text/plain - the vnd.cups-postscript filter would be "-" and the
text/plain filter would be your own custom filter program that uses
the CUPS PPD API to emit the proper JCL commands prior to printing
the text.

You'll want to define JCL options (see the PCL driver examples)
for each form, and then those options will be applied when you
print (the solution would support both plain text and PostScript
printing...)

FWIW, you can contact me directly for consulting rates, etc. for
this sort of thing, but this sounds like a pretty simple project.
