HP OfficeJet 4650 All-in-One can't set default to Black and White only
Product: HP OfficeJet 4650 All-in-One
Operating System: macOS 10.12 Sierra
I'm struggling to find where I set the default print settings for my new HP OfficeJet 4650 to black and white - so that Colour is not wasted.
Also, when accessing the printer settings, detailed settings are available through the browser, which keeps giving me an error message when I select Admin or Airprint pages (it says the connection is not private - even though I am on my password protected wifi).
Any ideas? This was much easier on my old HP printer that finally packed up after 8 years.
