QTR-Quadtone RIP

Epson R1800 - need to print some B+W images.

Discovered Quadtone, installed and set as the tutorial explained.

All seems OK, but when sending the first test print to the printer, it starts to print - giving "printing" percentages in the dialog box - then just holds/hangs with the legend that the printer is "in use".

The R1800 is working fine, attached to an Airport Extreme, and prints from everything i have tried.  The IP address i have is from the airport config.  MBP 15 3.06 Ghz Core 2 duo with 8 gig mountain lion 10.8.2 .  Gigabit network with cisco switches Apple WAP, using Aperture and iPhoto to try and print.

I tried to install manually (using Bonjour) , but could not get Quad Rip to show any curves.. even when i copied the name exactly (cut and paste) from the auto install to the manual.

Any help on this would be helpful, the need to be able to print B+W is upon me.
