QTR-Quadtone RIP

Gentlemen: I have upgraded my Mac Pro to Leopard. Prior to that I was using Tiger v10.4.9 
and QTR just fine. However, after Leopard, I had not tried to print using QTR. I find now that 
it will not work.

I have uninstalled and re-installed QTR v2.5.2 and the Leopard patch as directed and still 
nothing. I can see Quad2200-k7 in my "Print & Fax window and the printer shows Status = 
Idle and the Printer is showing "Ready". However, in the bottom window the "Status" shows 
"Stopped". No action on my part will change that "Stopped" status.

any advise will be appriciated,

Thanks,

Jim Otto
