My EPL-5700i has been a big heavy paperweight for more than a year and a half now. The OS 9 driver was terrible, but at least you could print. I have no (realistic) hopes of Epson ever releasing an OS X driver for this printer.
I tried GIMP-Print because it stated that the EPL-5700 (not "i")
might be supported. It didn't work with the 5700i.
At this point I'm looking at buying an expensive PostScript/Ethernet/Duplex laser from HP so that I never have to worry about drivers again. (PostScript printers can simply uses Apple's LaserWriter drivers.) I just have to be patient until I have $1000 that I don't need to spend on something more important.
