I was just given a brand new Epson R300 printer, which I installed today. Monitor is and NEC S-IPS 2070nx panel, calibrated using an i1.
To test the printer, I loaded an image into PS7. I checked the image in a custom proof setting, using the epson icc profile for the premium gloosy paper I have. I tested the image using both perceptual and relative colormetric to determine which one looked best.
I then went into print with preview. I chose the input space as my RGB working space, and the output based on the best soft proof. I then go into the printer properties, choose best photo, the proper printer paper, click ICM and turn off color managment.
The prints I get are close to the monitor, but sometimes have a bit of a color cast, and saturation is degraded. Also I loose a lot of detail in the shadow portions of the image.
Is there something I need to change?

Maybe try some Ilford paper???
