Isn't QImage a Windows-only program? If so means you are on Windows. If so means the Epson Preview (presumably that's the one on the LEFT is NOT colour-managed. Never was and isn't now. Presumably the Right image is what you see in QImage. If so, presumably that is colour managed. If so, and if QImage is behaving and you have only it managing colours, providing your display really is properly calibrated and profiled for your working and print viewing environment, there should be a decent match between the Right image and what comes out on paper. If there isn't, something else is wrong. If there is, ignore the Epson Preview on the Left if that is what it is. Not meant for anything more than checking that the print is sized and positioned the way you want it to print.
