QTR-Quadtone RIP

I am trying to figure out how to get QTR going.  And am under a bit of stress and deadline to get some prints finished  ...   so I will probably have a few questions.  I am quite a few days into bringing the system on line.


Right now I am setting up a 7600 with Cones K7   .. and in a month I will bring a 9800 with similar inks on line. I am using a mac pro with osx 10.5.7 and photoshop CS4.


I did all the set up work in the epson driver ...  and part of what I spent a great deal of time doing was figuring out the ethernet.  My office is very small ... so if at all possible I would like to use ethernet to get to my printers in the next room.  When I tried to use QTR I found no Ethernet option.  And have since noted it is set up for USB.  Is it possible to use ethernet??


Also I noted - "Attention to Mac users of Photoshop CS4 and Lightroom 2.1 under OSX 10.5 Leopard There are color management problems with B&W printing with both Epson ABW and QTR"  I am using cs4 with osx 10.5 ...  is this still possible ... what kind of color management problems are we looking at. I updated everything for this project. My old mac died and my old photoshop was the first CS.

I will probably have quite a few questions in the next week, but these feel like foundational ones  ...  I appreciate any help and advice.
