Go to system settings and select the 'Printer' option. Right-click on the printer and enable the 'Use Printer Online' function. Cancel all the printing jobs till that moment and redo the process. Sometimes the 'Printer Offline' message occurs due to a 'Job Stuck' issue. Check all network connections and functions. Be sure the network interfaces work properly. Turn the printer off and on to see whether the device is working properly.
To turn on wireless printer you need to check the printer cables and make sure that all connections are secure. Check whether any wireless printer cable is disconnected since this is the most common cause of offline printer cable. The second reason to solve this issue is you just turn off your wireless printer and wait for one or two minutes and turn it back on; this problem happens because of a certain glitch in your wireless network.
I had the same problem, and couldn't find a solution anywhere. My laptop said the wifi Brother MFC-255CW printer was offline, when the printer was definitely online and connected. In the end I simply went into Control Panel / Printers, selected the Brother printer, and deleted it off the network. Then I chose "Add a Printer" from the network, and reselected the only printer on my home network - which was the Brother MFC-255CW that I had just deleted. The computer reinstalled the driver, and everything was fine again - haven't had a problem since.
Hey Bud. I had the exact same issue with mine. I called around and no one had an educated answer. I remembered that my Uncle Lester works for the IP department for the city of Beaumont. I called his house and of course he was at work. Just for grins I asked his 8 year old daughter how to fix it. She simply said, "Just unplug the router and plug it back in.... What a ********...." Then she hung up... Neddless to say this seems to work for everything else too.... Good luck.
