You can normally do that by viewing the print queue. Once you submit a print job to the printer, double click on the printer icon in your thing tray at the bottom right hand portion of your screen. It should indicate how many pages are left in the print job. If your printer is technically able to do so, you can check how much toner is left through the printer properties. Go to start, settings, printers, and right click the printer you want to check and click properties. You should be able to navigate to the area that tells you the status of your toner or ink cartridge.
