Yea, we have a Epson 11800 64 inch wide printer. The cartridges are something like 700 ml for each of the 8 inks. We go months and sometimes over a year on some ink cartridges like Matte Black.
We can't get paper wider than 60 inches and we are limited to a 100 fool long roll. So in theory we could make a 100 foot by 200 foot print. I suspect that is theory. It prints at 2880 x 1440 PPI so the pixels are invisible without a magnifier.
