I've recently been testing the driver on an Epson 9900 with excellent results. However, I have just encountered an issue that will not let me print with QTR at all. Following is the info in the Terminal, Mac OS X 10.7.5 for the "quadtoneprint filter", since I have no idea exactly what it means or how to fix it.

/Library/Printers/QTR/filter/quadtoneprint ; exit;
ERROR: Fatal error: PPD environment variable not set!
logout
[Process completed]"
Any help would be much appreciated.
