sorry for stepping in here. I've been lurking on this list for quite
some time now but haven't posted anything yet.
Anyway, about one and a half year ago I started some work to see what I
can do with my Epson 5500W printer (one of those W*n only GDI printers).
I've put this work on the waiting queue and concentrated on porting
Linux to the Digital DECstations :-).

According to an old Powerpoint presentation I found on HP's web site the
first two bytes of the device id string describe the length of it. I
tried that with my 5500W and it works fine. Andrea, I do have user space
test program available which reads the device id of my printer in NIBBLE
and ECP mode and you may want to try this with your Epson Stylus. I'll
send the program to you when I'm back home, if you like.
