Hi Jean,
Thank you for posting your query in Microsoft Community.
From your issue description I understand that you want to check the ink level in windows 8 computer for HP Office Jet 6500.
To check the ink level you can follow these steps:
If your printer produces blurry, faint, or incomplete printouts, it might be low on ink or toner.
Many printers provide status about ink or toner levels directly on the device. To find out, refer to your owner's manual or go to the printer manufacturer's website.
You can refer to this links:

Some printers can inform Windows about how much ink or toner is remaining. Here's how to check:
a) Press” Windows + w” key to open charms bar with settings option.
b) Type device in the search field
c) Select device and printer
d) Click a printer.
If the printer is designed to provide ink or toner status, the information should appear in the status area at the bottom of Devices and Printers.
You can also double-click a printer to see more information about that printer.
For any Windows related assistance in the future, feel free to contact us and we will be glad to help.
