IRC2230 Mac Printing Issue

Customer has a Mac 10.5.8 PPC and all attempts to download a UFRII driver and install have failed. Below is the error message:

"cannot install UFRII/UFRII LT printer driver on your computer with this processor." check the operating environment.

Drivers we've tried:

C2230
UFRII_v10.1.0_Mac.zip "cannot install UFRII/UFRII LT printer driver on your computer with this processor." check the operating environment.
PPD_V3.50_Mac.zip the ppd failed...installed, but getting " PDL IMG Invalid data" at printer when I send a job.

C2030 to try an older driver:
UFRII_v2.43_Mac.zip "cannot install UFRII/UFRII LT printer driver on your computer with this processor." check the operating environment.
UFRII_v2.41_Mac.zip "cannot install UFRII/UFRII LT printer driver on your computer with this processor." check the operating environment.


Still no luck. Anyone else run into this?
