Ahha,
You have come upon the great truth of inkjet printers.
The printers are given away, or sold below cost.
The profit center is the ink.
Anyway,
From the start menu,
settings,
printers
select properties for your printer.
Set the default print mode to a lower resolution / quality, or even draft mode to use less ink.
(each printer uses slightly different names and dialog for this setting)
Click apply.
If you need a higher resolution for an important project, you can select printer properties from most programs, and select a higher quality mode temoporarily.
I myself use low to medium settings for most printing.
I also now use only 24 pound paper for nearly all ink jet printing. If you watch for sales, it doesn't really cost much more, and the print quality is much nicer.
