I have been using the Brother MFC-J6935DW printer, for almost a year, with Ubuntu 16.04 over wifi. Worked like a charm. Yesterday, I upgraded to Ubuntu 18.04. Most things went off pretty well. The only challenge I have not been able to resolve is that the printer starts spewing out garbage after the first couple of lines. The things I have tried are: a. Reinstall printer b. Download the driver from the brother site and reinstall that. c. sudo apt-get install lib32z1 lib32ncurses5 lib32stdc++6 (as suggested on another thread here). d. Reinstalled Ms fonts e. Upgraded to the latest firmware.
No luck as yet. Any suggestions, please? The only workaround I have at the moment is to print the pdf document as an image (I really need to get this resolved before my wife needs to use the printer!).
Attached is an image of what I get when I try to print a standard document. PrintOutSample
