Hi. Looking specifically at the Epson SC-P600, the GCR control is not working for me, I'm using 5.3.3 but this control didn't work for me with this printer in 5.2.x either. In the output control, the GCR Upper Contol goes from 0.000 to 5.000 (normally on other printers I found this to from from 0-1), the GCR Lower Control does go from 0-1
What happens at different settings?
I use this setting with other Epson printers so I'm familiar with it. With the P600 I have tried over a dozen combinations of settings it seems to have no effect on the output, looks identical
