Having searched the web for days, I cannot find a resolution which both addresses and solves my problem. I am using Macbook Air with Catalina. Trying to print with my 7520e but cannot for the life of me find an option to print in black and white only. The alleged 'Colour' drop down menu does not appear in my printer settings at all. I looked at both 'standard settings' and 'print using system dialogue' (see pic) but all to no avail.
I checked on the HP support site and downloaded the HP easyprint latest version but no change or improvement there either.
For clarity, all the cartridges are fitted and have ink in them - although I doubt this would affect the options available in a settings dialogue box somehow. The printer is used mainly for printing black and white labels and shipping lists but seems to get through colour carts as quick as black ones!
Grateful for any help offered.
Cheers!
