the only way is:
Draft for any drafts of cause or as hand outs etc

You need full fat printing on final works of cause, draft is useful for documents your changing and re printing all the time

Likewise print colour in mono until your ready mono is cheaper than colour

if you installed the drivers and monitoring software you can adjust all sorts of things like darkness, saturation etc etc all sorts

Depends what you printing on as well

Try less DPI as that will print quicker, less quality and less ink, again draft

Draft can become light and faint at times, highlights with coloured text printing in draft can be lost or hard to see

Some basic things to try first
