Brother HL-2240 not recognised by the computer

If you have already updated the printer driver, the firmware, and the HL-2240 is seen by the software and not by the computer that say that the printer is offline, it maybe means that you have several printers and you have to put the Brother HL-2240 as the one by default.

Go into the settings panel of windows, select the printer and peripherals, right click on the Brother printer and select set as the default printer. Windows should then be able to print the wanted documents with the HL-2240.
