Fire up the RIP, drop the image on the template, pick what size, what profile, and it just prints fine.
The same can be said of any good software... or Lightroom at least.
My 2 euro cents about the OP's question....
- I second that having complete control over the printing workflow is almost priceless, and something I just couldn't give away now. And seen from France, feppe's description of labs (apart from a few F-expensive ones) is alas so true!
- Color management is not that
difficult, once you understand the basic concepts behind it (see eg Real world color management
by Fraser et al. if needed), and mostly once you master how to fiddle with hidden options that do the right thing in the driver (it's a bit like shooting raw on a P&S : it should be the simplest thing to do, but it's hidden away from the user by
clueless coke sniffers
marketing services). However, once you know the trick for your printer and OS you're good to go.
The main problem with color management is getting good profiles, and from what I've heard, the SpyderPrint might be the weak link in your chain... I'd advise you to test a good custom profile (or first canned profiles if you haven't already) and see if that improves your workflow.
