I looked into the links you posted about gelatin/silver prints using an internegative process. Do you know of any print shops that perform this service? I gave up printing my own images a few years ago. I got tired of dealing with clogged printheads, etc. I use Costco for most printing, except the fine art prints I do on occasion. I just sent the two images shown above to Costco. You can't beat the longevity of silver based images, though. I just looked at some work I printed more than 45 years ago, still as good as the day they came out of the fixer (but not as good as I could do today).
Haven't used any personally but teg goog turns up several promising shops which you could probably research a little further before taking the plunge.
I like Keith Cooper's quote on the care & feeding of large-format printers:
when recently looking into problems with our iPF8300, I talked to several people in the ‘large format business’, and lack of use was the number one cause of problems.
If I had to put a big sticky label on printers it would be:
** — USE ME REGULARLY — AT LEAST ONCE A WEEK — **
I keep a 24″ roll of cheap proofing paper in our iPF8300 and try and make sure I print every week (a diary reminder helps).
