I print from home, I also have the r1900 and I find it as good and even better than some prints I get from labs. If I need anything larger than 13 by 42 I go to a printer, outside that I do all my printing at home, just find it more satisfying and I can print all I want, the cost is not bad, I use Epson 5 star paper, has an under glass life of 300 years, it is considered archival quality. Gilcee is what most printers use and it is just a fancy word for ink jet ink.

So I cannot see how a print shop can do much better. All depends on the paper and ink quality. I use prints I do at home in shows and sell them and never had anyone be able to tell I print at home. I print so much it is cheaper over the long run since I only usually do one or two prints at a time. If I need a run of over 20 of the same image I would just go to a printer. It also means I do everything from taking the photo to the final print and thats what I find satisfying.
