1. I'm running Fedora17
2. Until today I used the samsung drivers for my ml-1660 (UnifiedLinuxDriver_0.86.tar.gz) , but I wanted to get rid of them, because I had problems with the usage of ml-1660 in Libreoffice. So I got the advice from the Fedora-Libreoffice team to switch to splix. I did this although the printer is not listed in the "list of supported printers" on the splix homepage. And see, hurra, after having installed the correspondent rpm of Fedora-17 (splix-2.0.1-0.9.20120419svn.fc17.x86_64) I could install my ml-1660 with system-config-printer, and it runs well, and I got rid of all Libreoffice problems.
Thank you for your message. The website has been updated ;)
