Here you can find the solution for both Windows and Mac computers. Or I need an alternative printer driver or printer firmware.This post will provide you the easiest and simplest guidelines on how to scan a Paper on Canon mp480 Printer. a conversion which matches the printer resolution exactly so that there is no scaling.a dithering conversion, so that low-contrast text and images are visible.I just don't want to waste money replacing all my colour ink all the time while the black cartridge still has plenty of usable ink.Īfter this investigation, I think what I need is: Remember that I'm not being picky about how this looks. I thought those colour spots might be aliasing or encoding artefacts, so I scanned a laser-printed page and found no such issues. I thought this might be a result of the medium-quality print setting (perhaps scaling was involved), so I printed again in high quality:Įven the high-quality image on the right shows a few of coloured spots (eg., top right edge), and I wonder if the difference is simply that the black has over-printed the coloured ink more thoroughly in the high-quality case. I also found that even perfectly black text has colour fringes on it. In fact, on printing my perfectly black and white test page my yellow ink lever dropped by another bar. Even after these become black and white bitmaps, they'll still need to be scaled to the print resolution.Īs anticipated, this results in the black-and-white image being scaled with smoothing, resulting in intermediate greys which the printer renders in colour ink. Update: experimenting with Frizlab's suggestion to use the black and white Quartz filter in Preview's PDF save dialogue, I quickly realised that I was still going to have a problem with images.

I think there used to be filter options available in earlier versions of OS-X, which might have included something which would do this, but I don't see those anymore.

How can I do this easily from any application? Or, how else might I configure my printer to print using only black ink? I suspect that if I can convert the image to pure black and white with dithering (no grey) then the printer might then use only the black ink. To prove this I scanned a printout at 600dpi and got the following in what looked like a light-grey part of the page: I have a Canon printer and I have selected the 'Black & White' option from the print dialogue, but the result is that it prints in grey-scale, and the greys are rendered using the colour inks. I'd like to routinely print using only black ink when colour isn't important, because I have a whole lot more black ink than colour ink.
