I put Sabayon on a computer that does not have Internet access, but does have a printer (Epson Stylus C88+). Apparently the driver I need is gutenprint, but it's not already on the machine. CUPS tells me each time I try to install it that "either the driver doesn't exist, or you don't have the permissions to do this." I have the permissions, because I'm doing this in root.
The only package for gutenprint that I've found is an RPM, and Sabayon, sadly, is not RPM-based. So what file(s) would I need to put on a pen drive and transport to this computer, and once I do that, what should I do with them / what directory should I put them in so that the driver will be installed?
Thanks for any help on the matter.
