QTR-Quadtone RIP

Has anyone seen this?

When I try to install some curves you sent I get the following message in Terminal:

command ; exit;

*********************************************************************

Cannot find an Epson USB printer with the name 4900

After doing this I get The Quad4900 printer in Photoshop but no curves.

I am running Photoshop CS 5.1 on a MacBook Retina with OS 10.7.4 connecting to the printer via ethernet.

thanks,
