Need help on HP Color LaserJet 3600 PPD Driver

[Savan]

I am running CUPS on Solaris 10.

I found this PPD on the net and installed it:  HP-Color_LaserJet_3600-hpijs.ppd

This PPD driver does not work. What I need is a postscript driver (not hpijs).
I installed the closet one: HP-Color_LaserJet_3700-Postscript.ppd. This one does not work too.

There is no Postscript PPD for this printer any where on the net. Please share with me this Postscript PPD for HP Color LaserJet 3600. Thanks.
