Although I did some googling before posting, I didn't find anything useful.

Looking some more, I just found [link|http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&th=7967bf21c58a61b3&rnum=1|this] thread in Google Groups. It's the same error message I see with my 704P, but they're using the print server on a DI-713P. A couple of replies:

I had the same problem -- same setup (Epson Color Stylus 800, DI-713p). The solution was to install a new printer with the plain-jane driver called EPSON STYLUS COLOR ESC/P 2. It printed fine after that. However, you won't get the Epson Status Monitor which shows you the ink levels, etc. [...]

sounds like your talking about LPR is supported by the 713p, this may
still not give full Bidirectional support to the Epson utilities as they
probably don't understand the Ethernet interface, but here's how to get it
loaded on various WinTel machines try this utility for win9x/Me, they have no native LPR support [link|http://www.utexas.edu/academic/otl/software/lpr/|[link|http://www.utexas.edu/academic/otl/software/lpr/|http://www.utexas.e...oftware/lpr/]]


I'll give those a shot when I get some time.

[Added in Edit] I think I'll skip the UT LPR software. $79 is a bit steep....

Cheers,
