Yeah, that's the problem, but we can't help you with that :-)

AFAIK there is no 2d acceleration on the epson chip. To scroll page one pixel up you need to transfer whole frame to the epson chip again. There is scaling or pixel doubling(=2x scaling) with intepolation, color space conversion, rotation, but everything is applied on the fly to rectangle sent to the chip. There is no operation that can move pixels already transferred to the epson chip (=scrolling).
