Hi all, I experienced printer not working after cups update. I don't know if it is usefull for someone else, but I used gutenprint to be able to print on my Epson DX4800. After upgrading cups, in the web page of cups admin I see the messages: DX4800: "Filter "commandtoepson" for printer "EPSON_Stylus_DX4800" not available: No such file or directory" I didn't look for thi messages before to open bug in bugzilla and to involve developers to solve problems. So the question is gutenprint 5.0.0 rc2 compiled and installed on previous cups worked. Updating cups break printers Compiling and installing gutenprint 5.0.0 rc3 solved problems. I don't know if reinstalling old compiled gutenprint 5.0.0rc2 would also fix problem Bye to all Ambrogio
