Gary,
I get that you're frustrated with the results, and if I can I'd like to help you get better prints from Aperture. It's quite possible, as many can attest. There are differences in how an application like Aperture handles color printing than say an application like Safari. These differences can lead to some frustration from users who aren't used to printing from applications that rely on good color workflow for accurate and consistent results.
We tell you to calibrate you screen, not to be unhelpful, but because it's the only way any of us know to ensure that what you see on screen comes pretty close to what you get in print (they'll never be identical). Without a good calibration of your display, there is really no chance they'll match. Now keep in mind, that doesn't mean that regular, non professional folks aren't getting prints they love from regular ink jets everyday. Quite the contrary. My wife prints from iPhoto on her MacBook to our iP6700d all the time without a calibrated display or the proper icc profiles for the printer, and she loves her prints. I cringe when I see them, but keep my mouth shut, as they are too saturated and dissimilar to images when I view them on my screen. She thinks they're perfect, as what she considers a good "screen to print" match varies very much from what I require. She also, like many "non pros," prefers the more saturated, higher contrast, brighter images that the printers often kick out using the standard, non managed setting. More accurate doesn't always equal more attractive.
Aperture, in order to get really good prints, requires a good color workflow. That means a properly calibrated display, a good icc profile (created for your specific printer, paper, ink, and print settings), and accurate print settings in the dialogue boxes. Also, to see exactly what you're going to get on the paper, and this holds true for Photoshop, you need to turn on soft proofing within the application. If any of these things are off, your prints will be off.
I'm not saying you can't get a print you love from Safari or Firefox or whatever else you print from, I'm sure you can. I am saying that a print from Safari will never be as accurate screen to print as a print from Aperture built from a solid color workflow chain.
