Had to replace my Canon Pixma. (More undocumented ERR messages than printed pages
Now have a EPSON SX 230 for home use.
From the terminal as root a
rpm -i epson-inkjet-printer-201108w-1.0.0-1lsb3.2.i486.rpm
will do the job.
iscan-data-1.17.0-2.noarch.rpm and iscan-2.29.1-5.usb0.1.ltdl7.i386.rpm
Also do a rpm -i with both packages. DATA package first!
Did not find (or need?) iscan-plugin-gt-x750-2.1.2-1.i386.rpm
