QTR-Quadtone RIP

I have in the past printed using this computer and this printer with the RIP, but not in OS 
10.5.3.
When the rips show in print and fax and are selected the printer just does not print, it doesn't 
do anything.
No matter what we do it won't communicate with the printer using the RIP in any form. It 
sees the ink levels and it can do the tests but it won't print with the RIP. It will print using the 
Epson standard driver.
I have uninstalled the RIP numerous times- I have trashed it when it didn't disappear- I have 
emptied the trash restarted and re installed the rip. Nothing seems to work.
Help!
Or reply to teafree@...- I don't access yahoo address.

Thank you ,Tina
