To see what’s printing on a Windows device, access the print queue through the "Printers & Scanners" settings or by clicking on the printer icon in the taskbar. On macOS, go to "Printers & Scanners" in System Preferences and select your printer to view the print client. If you're using a mobile device or HP printer, most apps allow you to see a list of active print jobs. Additionally, video shows from Microsoft and other trusted sources provide valuable information on how to monitor your print queue efficiently.
