Your printer output will NOT necessarily be satisfactory for any purpose just because your monitor is calibrated. Some high-end printers such as the Epson 4000 can perform very well with Epson's canned profiles (at least in my experience with Enhanced Matte paper), but unfortunately, it is most often the case that you do need to profile your printer as well. The good news is that you need not spend $2300 to do this. If the canned printer profile is not good enough, there are a number of high quality commercial profiling services that will make a separate profile for each of the printer-paper combinations you require in the price range of 50 to 100 dollars each. You download their targets, print them according to their instructions, send them off for profiling, and they email back to you the profiles that you load into your profiles folder for use in PS.
As for the commercial stuff, if you know who will be printing your pictures, you should get their printer profile by email and load it into your profiles folder so that you can soft proof your images using their profile and adjust them accordingly such that the colors, brightness and contrast are the way you want them but in the soft-proof with their profile. That is the surest way of knowing that the printed result will resemble what you want to send them.
