It seems, a lot of people refer to your printer as iR3570, so.. perhaps you'll find more.
I did find a few references claiming that printer supports RFC1179(LPD/LPR protocol).. as in, it might have a built in daemon.

So, forget CUPS.. configure lpd.. send postscript/text to it? lpd will allow you to specify a remote printer by IP/hostname..

I hate new printers, dot matrix ftw...
