I'm leaning towards starting with Dye Sub / D2T2 or (one of its many other names it's known by) in the $500 range, and printing to it via Lightroom.
I have the problem the above two posts describe with my HP OfficeJet G85 (archaic now, but was expensive when new). I use it so infrequently, I have lots of problems with the ink cartridges. I don't remember the last time I had a good print let alone color print from it. So using a technology where the color medium is embedded in the paper is an attractive one to me.
Why I'm doing all this, I want to cover the walls like a wall paper (not using any frames) of a small bathroom of mine with the better photos I've taken. I know, if I add-up the square footage and calculate out the cost to print, I might re-think the whole thing.
So ignorance is bliss.
