I have a Mac Mini (late 2012) with Mavericks installed. It is connected via USB to an Epson Stylus Color Photo R200 inkjet printer.
When I print, the print job window says
Stopped - Unsupported colorspace = -1, 2 pages
I have run Software Update. This is the first time I have tried to use the printer, normally it connects to my old PC and works fine.
