If your printer is offline and you can't print please try the steps below.
1. Open the Start menu and search for devices and printers and select it. This will open a window with a list of the printers currently set up on your computer.
2. Right click the printer you want to change to online and select See what's printing. A pop-up window detailing all current print jobs will open.
3. Go to "Printer" in the menu bar at the top of the pop-up window and uncheck "Use Printer Offline." This action will change the printer from offline to online.
If this does not work continue on to the next step.
4. Is anyone else around you having this issue? If no, please restart your computer and try again. If the answer is yes please restart the printer and try again.
If you have tried all of the above and are still having an issue, please submit a ticket.
