Here’s what to do for the Dell Printer Offline error. Find the device manager settings in your control panel on your PC. To open the list, scroll to the USB controller section and click the plus sign or arrow. Further, right-click each USB Root Hub and select Properties. Now, pick the Power Management tab from the drop-down menu. Uncheck the box that says Allow the computer to turn off this device to save power. Additionally, restart your computer if necessary. Finally, go back to step one, scroll to Network adapters, right-click the wireless adapter > properties > power management, and untick the same option as in step five.
