I think not.

What confuses me is that with dmesg or disconnecting and reconnecting I see:

Feb 28 11:50:35 ed kernel: ulpt0: at ushub0, port 2, addr 2 (disconnected)
Feb 28 11:50:35 ed kernel: ugen0.2: <EPSON> at usbus0 (disconnected)
Feb 28 11:50:39 ed kernel: ugen0.2: <EPSON> at usbus0
Feb 28 11:50:39 ed kernel: ulpt0: <USB2.0 Printer> on usbus0
Feb 28 11:50:39 ed kernel: ulpt0: using bi-directional mode
Feb 28 11:50:39 ed kernel: Symlink: ulpt0 -> usb0.2.1.16
Feb 28 11:50:39 ed kernel: Symlink: unlpt0 -> usb0.2.1.17

But cups still says:

Unable to open device file "/dev/ulpt0": Operation not permitted"

and there are no lpt devices in /dev or subdirectories.

Any additional suggestins apreciated.
