How do I tell ink levels - HP Officejet 6500 AllInOne InkJet Printer

If you need drivers printer > https://supportdrivers.info/

If you have Windows 7 you can check this by clicking on the "Start" button at the bottom of the screen, click on the "HP" folder and click on "HP Solutions Center". A graft will come up showing you the printer cartridges levels. Click on the small graft chart at the top right of the screen and the graft will enlage and show you exactly the staus of the ink levels. Click "Print" at the bottom of the screen and it'll run a print test. All 4 cartridges need to be above the "Low" level. It only takes one of them to mess up the print.
