I just reconnected my Epson printer to my year-old iMac running Snow Leopard, but when I try to print, I receive an error message about missing Libraries, which I took to mean a driver. I tried to download a new driver from Epson, which instructed me to run a software update. I did that and found one file to update. I completed that update, but I'm still unable to print and am receiving that same error message. At one point, I found another screen at Epson about problems with drivers and Snow Leopard that mentioned I should be sure to have Rosetta running. I cannot locate Rosetta on my hard drive. Apparently the only way to install Rosetta is through my OS disc(s), which have been misplaced during a recent renovation. Any suggestions would be appreciated.
