$80/roll, you can get roughly 33 36" prints from that 100' roll, so right around $2.50 per print for paper - ink will depend on the individual image.
After being a longtime advocate of lab/online printing (MPix specifically,) I just jumped on the home-printing bandwagon. I was amazed to learn that the current home photo printers have a much broader gamut for color than MPix did, which may or may not mean anything to an individual photographer. Certainly it makes it easier to turn out images that look fake or "cartoony." But if you're into that super-saturated HDR look, it's definitely a better way to print
I was also surprised to find that the printer I purchased (Epson 4880) seems to hold shadow detail better than the equivalent print from MPix. I realize that it's VERY profile-dependent, but I was still very surprised to see that.
If you're only ever printing 4x6 or 5x7 with the rare 8x10 thrown in, printing at home will likely never pay for itself. But I'm of the opinion that if an image is worth printing, it's worth printing 8x10 or bigger. That "or bigger" can get expensive in a hurry. Being able to crank out 17"-wide prints (either 17x11 or 17x25 for a standard DSLR image) at roughly $2 per linear foot makes the proposition of buying a printer a whole lot more digestible. Especially when you factor in MPix minimum $7 shipping cost.
Epson has some OBSCENE rebates going until the end of the month, and for the difference in price between the 13" 2880 and the 17" 4880 with roll feed, you basically are just paying for the extra ink they include with the printer. That, combined with SIGNIFICANTLY lower ink costs per-mL down the line, and it was the way for me to go.
And truly, I was the one saying that printing at home could never compete with a pro lab. And logically, I didn't believe that I could afford to put a machine in my apartment that would be able to out-perform the high-end machines MPix prints on. But with just a few prints out so far, I can unequivocally say that it does in fact generate better output. And now I can fire off a 17x25 in my living room, and 30 minutes later it's sitting in the output tray. That's a heck of a lot better than the 4-odd days I used to average with MPix.
