If I use 70% grey instead of black when I print

Factual Questions
1

am I really saving 30% on ink?

and would this be true with both color and black and white?

( I know printers sometimes use black to help out the colors and would guess it might work the other way around as well)

Use economy print in options, ant the lowest resolution that is the best you can do to save ink It will be a single pass single dot print. with out the over lapping that the better options use.

You can use a photo application and lighten the picture to save further on the ink, but this is because the photo is now lighter and has nothing to do with the printer software. The photo program will send white areas in with the colored areas to cause a lighter picture. You will be printing less dots with ink than using the economy print driver would do. Actually some of the print drives can now be set to print like what you had to use the photo program to do before.

If you have a color printer, the grey color will likely be printed by the color cartridge, not the black one. You could confirm this by taking the black cartridge out before printing.

I will agree with this. Gray on modern inkjet printers is printed by combining the other colors to render gray, not by dithering the black ink.

Doesn’t that depend if you have a 3, 4 or 6-color printer?

It’s a great way to save on black ink. You won’t ever run out of black ink by printing everything in grey.
