Printers and Printing - I know

I run Windows, so Aperture isn't an option for me. However, I find that printing in Lightroom 4 is outstanding. I use a Colormunki to calibrate my screen and create paper profiles, then use Lightroom's soft proofing to check how my printer's color limitations will affect the print. My prints and my screen are as close to identical as possible given that prints are reflective and screens are a light source.

ps. A friend who does all PP in Photoshop only prints using Lightroom with an Epson 3880. He likes Lightroom's print module that much.  If you think you'll primarily use Lightroom I highly recommend Martin Evening's book on it.
