For black and white, traditional darkroom enlargement.
For slides, ilfochrome whenever possible.
For other color work, an Oce Lightjet or Durst Lambda, though a printer on MM offered me an 11x14 metallic print on a Chromira, so we'll see how it stacks up. He claims he's owned a LightJet and thinks the Chromira is better.
I really do love black and white prints. So much so, in fact, that I'm having a 4x5 negative printed on an LVT of
this image just so I can print it on a true black and white paper.
I've thought about printing edited color images onto chromes so that I can print Ilfochromes of them. Boy you haven't seen a color print till you've seen an Ilfochrome. On the other hand I might just mail a cd off to a lab somewhere else. The LightJet at my local pro lab is only setup to print RA4. If I could just find a damned 4x5 attachment for a ProPalette I'd be doing it myself.
I also print from time to time on an Epson 7800 for color work. I have a stash of 20x24 glossy Ilford Media Board that makes very nice poster/presentation style images, and at about 1mm thick it requires no matting. For some reason, that particular "paper" will not bronze no matter how much ink the printer lays down, which is something I occasionally have a problem with on semi-gloss and lustre papers. I've been meaning to toy around with Hahnemeuhle's matte rag papers but I just don't care enough about inkjets at the moment.
