QTR-Quadtone RIP

I down loaded 2.4.1 about a year ago  

I had difficulty with the install  ... and a lot of work so I let it
sit.  I am trying once again to see if I can get it to work.

I figured out the install   ...  but I can not get it to find the
printer.  

Everything showed up on "print with preview" correctly, "page set up"
was correct ... and on "print" quad rip shows up .. I set the two
curves, set the printer ... press print. And it does not find the
printer. I did a reinstall  ...  still can not find the printer. The
Quad4800 icon shows up in the tool bar computer starts to cycle the
print, but there is no response from the printer and then the icon
disappears.

I am using a Mac OS X  10.3.9 with an epson 4800 ...  Epson K3 ink...
I have it hooked up to the computer with an ethernet cable.

If I change the printer setting in "print" from Quad4800 to
StylusPro4800-B9249F  it works with all the same settings  ...  ugly
print but it can find the printer.

Any suggestions  ... I am dyslexic so I sometimes have problems with
all the names for things on a computer program and instructions.

The only thing I can figure is I do not have the correct address  .. I
am using IP address from Systems Preferences - Network - Built in
Ethernet : TCP/ IP : IP Address.  Is there away to find out what the
ethernet setting is for StylusPro4800-B9249F.

any other ideas?

thanks
