Do inkjet printers use colour ink to print grey?

I need to print out lots of trial pages and I wondered whether it would be worth it to try and save my colour ink by printing out everything grey... but if the printer uses a mixture of the colour ink to create grey, this won't work... any help?Do inkjet printers use colour ink to print grey?
Unless the colour is 100% black or text, most printers will use the cyan, magenta and yellow colours to create a ';muddy black';.





Your printer should allow you to ';print all colors as black';, or more precisely, shades of grey.





Click ';Print'; and then the ';Properties'; button to open the printer settings panel. Look for a small check box that disables colour printing.





That should do the trick.Do inkjet printers use colour ink to print grey?
It depends. Usually, the printer (in windows) has a setting that says print black and white or grayscale. If you select that, it should not use color inks. However, if you print grays in color mode, it usually will use some color ink.
Unfortunately almost all ink jet printers use a mix of their cartridges to print.


Print yourself out a black bar and take a close look at it, if you see any blue, then you may as well use colour.
It depends on the printer. If the printer has a black ink cartridge it typically uses just black. If it doesnt have black and just the other colors then it will use all the colors to create the grey.
no need...... Black and white ( or even Black only) Ink can produce gray colour =3
