If you have a HP printer, you should have installed the HP Solution Center software. If you don't have the application, go to HP Drivers & Downloads page, identify your printer model, select your operating system and download the provided files. After that, go to Start > All Programs > HP and open the HP Solution Center. Click Settings, navigate to Print Settings and then press Printer Toolbox. After that, select the Estimated Ink Levels tab and you will see two graphics displaying the ink level. For further information, check the HP Consumer Support page.
