At office I am using HP Officejet 4620. This printer is using too much ink. The cartridge end up really fast. We are taking a few color prints. Most of the time it is black and white. I am unable to figure out the problem here. At my home I am having different hp printer. It works for long time. I think within a month the cartridge of HP Officejet 4620 drains out. Is there a point available through which I can reduce the ink usage.
