Funny that the Epson ET8550 was only mentioned once, so. For a more casual use, as in not trying to sell A2 sized prints, it works great. Ink is cheap, you actually only have to worry about paper cost. Epson claims 10+ years before ink fades, in an album or something similar it should hold up forever.
And running the numbers, I did before I bought mine, doing these kinds of break-even calculations at work for certain things helps, shows it is cheaper per print than a lab (write off of the printer in 12 months with a total of 200 10x15 cm prints). A lot less than that when it comes to A3+ sized prints (using the normed test numbers of prints per cartridge, it kind of scales linear for the same kind of print).
Regarding quality, even someone like Keith Cooper, you should look up his detailed, down to earth, real life reviews on printers, says he'll happily hang prints from an ET8550 on his walls.
For ewat its worth, printing helps to improve your photography from composing and taking the shot to post-processing.
Which reminds me, I have to do some printing again of some pictures.
