I have been trying to get my Epson Workforce 435 all in one wireless printer/scanner to work in Ubuntu 12.04 and no luck. For now, my OS is running within an Oracle Virtual Box VM. I have downloaded the following driver packages from Epson:
I installed both of them. I then used the printers menu item to install setup the printer. All goes well. But, when I print a test page the status message in the Document Status dialog box says:
Held for authentication
When I was adding the printer, I was prompted to enter my login and password. I don't understand.
