Digital BW, The Print

I get these fine white lines and I use the Epson driver, and speaking of
driver, they driver me crazy!

I think it must be some sort of timing error between the head firings and
the transport mechanism. In any case it would appear to be independent of
which driver is used.

They come and go on my machine. Unfortunately they decided to first come as
soon as the warranty expired. :-/
