Epson SC p600 works fine with Default RGB and Default Grey icc profiles. If any other icc is selected (tried Argyll and proprietary profiles from PermaJet) print is stopped. Job Attributes table shows job-printer-state-message Filter failed and job-state-reasons job-completed-with-errors
For the Epson driver for this very fine printer,
go here http://download.ebz.epson.net/dsc/du/02/DriverDownloadInfo.do?LG2=EN&CN2=&DSCMI=62074&DSCCHK=491da99ba16aace3a07d40439367278e7a3319f2 and click to download what for 64bit Ubuntu should be epson-sc-p9k8k7k6k-ww_1.0.0-1lsb3.2_amd64.deb
(Epson specifically call this a FULL-FEATURE driver so we hope it is very good)
(I am guessing ww means worldwide, as there seem to be specifically japanese drivers further on in the list.
If when one clicks to download, the system offers to "OPEN" the package, accept that as OPEN means install
to set up a printer, one needs to 1) install the drivers and 2) register the printer with LPadmin; ... usually doing 1) seems to trigger an auto 2)
If you now have 2 icons, you need to be able to identify which is the Epson driver
