I find that if I turn my monitor brightness way down and set the gamut up a little, plus lighten the image in Gimp it works pretty well--and even then some images still print too dark. You need to get the ICC profile code for the printer you will be using and add it in Edit>Preferences>Color Management>Soft Proofing add your monitor and the ICC profile for the printer. The soft-proofed image will be more or less what the print will look like--except, as above, if your monitor is too bright it will be dark. Do a sample test and then adjust acordingly.
the need for a consistent color management workflow is very important, that's my take from the feedback above.
But still. If one enables soft-proofing in View > Color Management (proof color option), why is that the display does not change as dramatically as when one opens the printing dialog? It seems like as if soft-proofing is not working in Edit mode.
