This has only been done for rawtobr3 as far as I know. Reverse engineer and compile the required parts for ARM.However, if you are using RPi the emulation layer will make it terribly slow. Run i386 code on ARM through an emulator.So, how do we port the closed-source driver to another architecture? There are several methods: It fails part way into a print on large images or busy pages. Although there is an open source Brother Printer driver, it is not optimizied for cheap printers with small cache. Why? The Brother provided Linux drivers have parts that are compiled for i386 and have no source code. Brother printer drivers for Raspberry Pi and other ARM devices
