I'm a new user of GIMP 2.6.11 for OSX, and I can't figure out how to make photo colors print correctly. My printer is an Epson 2200, driver version 8.37. When I print one of my old photos from Mac Preview, colors come out the same as they did when I used this printer from Photoshop 6 on my old Windows PC. When I print the same image from GIMP on the Mac (using the Print command, not Gutenprint, and selecting photo quality and specifying the right paper, etc), the colors are too far off for a simple CY, MAG, Y level adjustment to get back to what I expect. Under image properties GIMP says the color profile of the image is sRGB IEC61966-2.1, and the image appears the same on my monitor in GIMP as it does in Preview. But it appears GIMP may be using a different color profile for printing than for display. is that possible, and if so, how can I change it?

Why don't you use gutenprint?
I have an Epson RX560.
Gimp + gutenprint give me very good prints. Gerard.

I tried Gutenprint once, but it seemed to ignore my instructions on what size to print. I'll try it again and see if I can sort out the sizing problem. Thanks for the idea.

Sizes can be set with "custom".
I experimented with odd sizes and it worked quite well. There are limits:It should be long enough for the paper transport to handle. Another important factor is your Gimp calibration. For instance when you set image size to 150x100 mm it should measure that on the screen at 100%! (Or in inches) I use gutenprint-5.2.6.
