If the receiving device has an ECP printer port then this is bi-directional and should allow you to read data from the printer port of the sending computer.
So: ECP-capable USB/parallel interface + what I'm going to call a "laplink cable" (parallel cross-over) should get me started? That's just what I wanted to hear!
Will the port appear as something I can read under /dev/xxx or will it be more complicated?
see: http://retired.beyondlogic.org/ecp/ecp.pdf from the wikipedia page http://en.wikipedia.org/wiki/Parallel_port.
Useful stuff, thanks.
Should you need a set of Epson codes, including how a bitmap image is built up I have the information buried on my website. I can dig it out if you want it.
I'll let you know! Thanks again,
