It may work for the 1270/1280 mentioned in the original question, 
but they use dye based inks so they're not very archival.   Using 
the stock Epson inks and the stock Epson driver for pigment-ink 
printers like the 2200 will result in metamerism.    You need to buy 
a RIP with its own driver to get around that using the U/C inks.
