This program (which is FREE) that saves ink or toners in your printer was recommended to me, so I tried it and was very happy with it. You have to apply for a Licence Number, which they email to you.
It puts you in control of what quality printing you need. If you want to print out a Bank Statement that only needs a light print, just slide the scale to your requirements. If you want to print a photo you simply slide it up the highest quality but of course it won’t save you any Ink/Toner by doing this. It can also omit any graphics if you want and just print the text.
