QTR-Quadtone RIP

Hi,

I am a QTR rookie and have an Artisan 50 Printer. It does not seem to be supported for QTR. But since it is the successor of the R280 I still have hope to get it installed. 

Does anyone have some experience with this printer?

I tried to run the InstallR280.command from the R260-R380-1400-CL folder, but I get this error message:

>Cannot find an Epson USB printer with the name R280
The printer must be turned on, plugged in to computer and ready
Resetting the printer may be necessary...<

By the way: Is it worth to install QTR for this printer?

Please help
