I have Epson too, just different model- Stylus C90. It never had its own driver, but on PCLOS 2009 worked fine on C68 driver. But is no longer working on 2010 beta2. It prints black page. Any other driver - the same result, drivers higher then C70 just scroll the paper. I tried the driver from http://www.avasys.jp
for C90, but didn't help - still prints a black page.
So far I managed to make my printer work on simplified C68 driver. It cuts a little bit from top margin, but otherwise works, although has limited setup possibility of course.
