A possible reason behind the HP Printer offline issue is also may be that all the Printer jobs got piled up which is creating the offline issue. A user has to cancel all the documents from the Devices and Printers page of the Printer to resolve the issue. You can also check the status of your Printer from the Devices and Printers page of your computer. If the Printer’s status is offline it means it is offline and if it is paused, it means you can turn it online
