Digital BW, The Print

I also had some issues with streaking recently, however this occurred when printing 2880 dpi bi-directionally and was solved by switching to uni-directional printing.  This does make printing a lot slower.  It was most noticeable on thick matte paper mainly an inch or two in from the left edge.
