Hi there,

I need some help to set up my Epson et-2750 inkjet printer. It is connected to by PC via a usb cable.
I downloaded and installed the EPSON drivers and utility - the scanner works perfectly, but the printer doesn't.

When I use the menu setup, it sees the printer but I can't print the test page.
Wen I use the CUPS web interface - same problem.

ls -l /dev/usb/lp*
ls: cannot access '/dev/usb/lp*': No such file or directory

Is this the problem? If so, how do I create lp0?
