I have always used an Epson 1280. Not a bad printer. The reason I have stayed away from Canon i950 is that it doesnt print anything larger than 8.5x11. I frequently print panoramas or square images that need a something bigger than 8.5 inches.
I really need to test some others out. Printers are expensive though

. I have done some experimenting with inks and papers, though--since most of my work is black and white, I needed to find a good, rich black that doesnt look pasty like most photo printers print.
