How to Get Back Online on Brother Printer Offline
First, check if your Brother printer is turned off or in Sleep mode. If it is turned off, press the Power button on the printer's control panel to turn it on. If it in sleep or hibernate mode, hit the Home button. If your device runs on the Windows 7 OS, click the Start menu and type 'printers' in the search box. Press the Enter key and choose the Devices and Printers option from the search result to access your printer settings. Locate your printer in the Printers and Faxes section and give a right-click on it. Next, select the Set as default printer option from the pop-up menu. Doing so will fix the problem. If the printer offline error remains unsolved, open the printing preferences window on your computer and verify the printer compatibility. If necessary, remove and reinstall the printer driver.
