Go into your printer software and setup ink saver mode, as for most printing the output will be fine and if you need to print something special you can disable it for that particular print job.
Also make sure your printer is set for the paper your using as otherwise this will also use ink unnecessarily. (E.g. printing on plain paper with the printer set to inkjet paper will eat up the ink a lot faster)

Hope this helps
