In my Epson 1270 printer driver I can choose either one. What is the difference? I would have thought they would amount to the same thing, that in each instance the printer would simply print the information passed on to it by the application. The other alternative, of course, is ICM Handled by Printer.
They evidently are not the same thing, though, as evidenced by the difference in colors that were produced when I printed some color targets out of Monaco EZColor, first using ICM Disabled and then using ICM Handled by Host.
