Any other R3000 owners experience this?

I've got a Canon 50D and the pics look fine on the camera and fine on the screen before any processing is applied. But if I print without brightening, the prints come out much darker. Other than that, the printer produces great prints. I understand that the pre-print viewings are from back-lit devices, but it seems to me that I shouldn't have to pre-brighten just to print a pic taken with default settings.

I print mostly RAW or JPEG directly from DPP to Epson Ultra Premium glossy paper and have my paper settings to reflect that (including 11 mil thickness).

I have also tried printing from Windows Live Photo Gallery, but get the same results.

Any input appreciated.
