Also, I know it works fine as cable because I can connect another printer with a parallel port for which I do have drivers, and successfully print a test page on it over that cable.
Using the same computer as the one you are trying to get it working on with the receipt printer ?
I must be doing something obvious wrong, but what? How do you address the usb port directly and just send it a stream of text, as in my present setup? Is there a way?
I think the kernel logs might give you a clue as to what device node the parallel port is appearing as..personally having not used one of these I would have expected it to just appear as a parallel interface and not under USB.
AFAIK these things provide a parallel interface to the host in the same way that plugging in a PCI one would do...I think you are expecting it to work like a bit of cable where you put USB commands in one end and get parallel ones out of the other, but USB doesn't work like that. In fact your computer should just think it has a parallel interface installed now and you just need to find out what device node it is on.
