QTR-Quadtone RIP

Hello,

I have been testing for a cyanotype curve on OHP for the Epson 4880. I 
printed my tests on 8.5x11" and got really good results. I want to 
print the final results on 13x19" OHP, but every time I initiate a 
print sequence, it stops two inches into the print. IThe printer 
doesn't send an error message. I simply have to halt the printing, or 
wait five minutes for the printer to spit out the film. I was able, 
however, to print the 8.5x11" test file on the 13x19" sheet, but it 
will not permit a full sized image. I'm very frustrated at this point. 

I am using the latest QTR and running it on Leopard. I have have 
deinstalled it once now, and threw away all related profile info. 
PLEASE tell me what is going on. I will be very greatfull.

Chris
