Thanks, Roy. The Epson driver offers high speed = off, in addition to unidirectional / bidirectional. That’s what I'd love to see in a future version of QTR. In the meantime, if you get a chance, please compare the print speeds on the R3000 (QTR versus Epson @ highest resolution, unidirectional) and I think you'll see Epson (with high speed off) is slower than QTR and smoother throughout (not just top / bottom). That’s what my test showed, but maybe I'm missing something.
