I'm currently putting together a small scale portfolio of my work... I have a great A3 printer, Canon i9950 and am for this task using a Macbook. I didn't imagine I'd have any huge issues here, but the difference between the brightness/blackness between my screen and the prints is pretty drastic. The prints really only become acceptable when I up the brightness/fiddle with the levels of my photos, and by doing so they look awful on screen... but look a lot better on paper. It is however, quite a trial and error method and aside from being sick of wasting expensive paper its just a daft way of working. I don't really want to resort to buying calibration hardware such as pantone colorvision (though I hear its pretty decent)... Truthfully, my screen is usually set to maximum brightness, but this is also the case with a windows based laptop I also use, and I have never had the same issues with screen/print differences. I don't know much about Canon colour management, but I'll go into all that if it looks like I have to. Is it a case of Canon printer/ink and paper to be closest to accuracy in this case? Any thoughts?... or is this just going to be another random hitch in my Mac-move?!
