Alternatively try googling "Parallel Printer data capture" or "Parallel Printer Capture"
I tried similar searches before but found software for capturing the data going out of the printer port, which would be fine if the printer was attached to a PC, but it's not :-(
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. see: http://retired.beyondlogic.org/ecp/ecp.pdf from the wikipedia page http://en.wikipedia.org/wiki/Parallel_port.
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.
