Interesting...  I've got an Epson RX-80 hooked up to one of my machines.
It worked fine with the screen dump, but...  What you describe is what
I got with Paint_Power output.  I built a little filter to change the
printer setup commands in the Paint_Power output file and pipe it
through the filter on the way to the printer.
