If you have your printer connected to a computer, it will allow you to see all the details and settings of your printer. This is how you can check, how much ink does my HP printer have? Turn on the printer. There must be a Windows notification area at the bottom-right corner of your desktop. You would see a printer icon. Click on the printer icon. You will see a drop down menu. Select the “properties” or “preferences” option. The ink levels are displayed in the printer’s setting window for the currently installed ink cartridges.
