Not an exaggeration...my workaround is to preview all my docs before printing them...forcing the preview button to launch a classic version of acrobat reader, then printing through classic. The docs come out right away, but therefore is the only reason I need to launch classic at all.
I'm looking for a way to speed up the os X epson 5700 driver so as not to do this...OR to find a hack or gimp-print solution.
