QTR-Quadtone RIP

I have having trouble with my Epson 2200 printing with the QRIP. 
Sometimes it works and other times the paper will not feed through
the 
printer.  It begins the process then abruptly quits before any
printing 
has actually taken place.  I eventually receive a message telling me 
there is an error.  I updated to the current version of QRIP hoping
to 
eliminate the problem, but it didn't help.  I am open to any 
suggestions. Dee
