Having very similar issues to "carlossl".
Running Ubuntu 13.04, an EPSON LQ-1070+ (running the LQ-570+ drivers, which work fine) and a "QinHeng Electronics CH340S" USB to parallel connector.
On a 12.04 machine I could use the printer with the regular parellel cable.
The only real difference is that I have no /dev/usb/.
If necessary I can upload all the output, but as mentioned before, very similar to the ones from "carlossl".
