Unsupported color space pboblem

April 2014:

My new mac pro (2013) will not print an ordinary rgb file from Photoshop CS6 to an Epson 7800 inkjet, giving an ‘unsupported color space’ message no matter which color space variation I try. (Mac os 10.9.2 + the latest Epson drivers)

The same file prints readily from an old mac pro (2009) with the same OS version, Photoshop and Epson drivers)

May 2014:

Now updated the OS on both macs to 10.9.3 - problem persists!

Comparing photoshop print procs on the 2 macs the older has an extensive extra list of Epson profiles (more than 30) Does anon know where these are stored? I’ve tried copying printer files from the library of old to new mac but nothing epson-related shows up…

I can manage by swapping files from new to old macs but surely SOMEONE should be able to help!
