I'd like some advice on how to print grayscale images on the canon mf267dw laser printer.
If I print a color image straight to the printer, it appears not too bad.
But when I print from ANY other program, for example Gimp and grayscale the image first it appears with horizontal lines through it. The horizontal lines are not missing ink - so no need to maintain the printer (it doesnt do this when I print straight from a color image).
So is there an ysetting I can change to experiment with printing from grayscale images to fix horizontal lines ?
Thanks for reading.
