HI. I am working with Knoppix 3.6, HD install. I installed my printer, an Epson stylus color 670, within CUPS. At this point I got no errors, so I suppose that all is OK. The printer is connected via an USB port.

But when I try to print... NO NOTHING outputs from the printer, even the test page. A message says that the page was printed successfully, but really the printer does nothing - it even does not try to load the sheet

What I am doing wrong?
