The message comes up in a big black box and there isn't an option to print grayscale of black

 

Printing Black and White Photos

Hi EAP1943

Are the photos black and white or are you trying to print color photos in black and white?

When printing the photos, do you go into the printer settings and choose to print then in Grayscale?

If you are printing photos and do not choose Grayscale printing, then all the inks on your printer are used and may result in a blue tinge, if you choose Grayscale Printing then only the black ink is used on your printer for the printing . . .

Please see page 140 of the manual for your printer, for setting that up:

How to find out if my printer supports true Grayscale mode?

Upon recommedation of a vendor I have purchase an Canon MG6600 for home-use. However, upon trying to print documents in grayscale, I have found that it will use the color cartridges: If one of them is empty, the "gray" suddenly turns into colors, and light grays might be missing entirely from the print.

Previous color-printers I used were able to operate without color cartridges, when grayscale printing was requested. These printers usually create different brightness levels by placing black spots in different densities, but that should apply for different intensities of any coloring agent. Hence the Canon MG 6600 should support this too, at least hardware-wise. Note on the example below, that some of the areas are actually grayish!

How can I find out if a given printer supports such a true grayscale mode?

What I have tried

• When printing PDFs from within Chrome, set "Color" to "Black and White"
  
• Windows 10's "Settings > Devices > Printers & Scanners > Canon MG 6600 Series Printer > Printing Preferences", I have enabled "Grayscale printing".
