Brother HL-1440 Disappears From Mavericks
I fixed my printer by installing a new driver after deleting the Old printer in System Preferences.(just hit the "-" button.)
Then Download and install this:

After that, go to System Preferences and add ("+" button) the printer. If it doesn't show up, check that it is plugged in and turned on, switch it off &amp; on or take out the USB cable &amp; put it back. Then it will appear. Remember to set it as the Default printer.
