Hello,
I'm having problems printing with my Epson C84 too. I've upgraded to OSX 10.6.1 / Mac Pro. The printer was fine on my previous OSX 10
After downloading from Epson the new driver for 10.6 and then adding the printer in the system prefrences, when I print something, I've had 2 issues:
1. The paper was fed through the printer with nothing printed
2. and now after trashing the 'Epson' folder from the HD/Library/Printers, I get a 'pause' when I print - and an error '/usr/libexec/cups/backend/usb failed' when I resume.
Did you get your printer to work again after trashing the Gutenprint driver? If so, how?
Thanks.
