When I first installed Zorin, I connected my Brother HL-L2390DW printer with a USB cable and I was able to print successfully without any effort. Later, I tried to get wireless printing working, so I downloaded a few Linux drivers from Brother's website, and I tried a few things but I never quite got it working properly. And now, the printer isn't printing at all. It just spews out blank pages continuously when I try to print.
How would I find and remove any printer drivers/software that I manually installed, and try a clean new install from Brother's website, which says "The tool will install LPR, CUPSwrapper driver and scanner driver (for scanner models)." I'm hoping that everything (including wireless printing) will work seamlessly after installing the manufacturer drivers.
