Your printer manufacturer should have an html or pdf formatted users manual
that will describe how to use your printer's function buttons to check the
status of the cartridges.

properties page for your default printer.
click - Start menu, settings, printers and faxes, find your default printer,
right click on the pop-up menu, select printing preferences. Find the service
tab.
