Comment 5 for bug 1363670

the driver appears to be corrupting the printer in some way. brother has the same problem even in their windows drivers, at least in earlier versions. the only "fix" is to break up every print job into 1-page documents, send 1 page, let it print, reboot the printer, delete the printer, re-add the printer, send the next page, etc... until you finish printing. this is really poorly designed. may only affect the USB printing. brother says "direct printing" works just fine. i take that to mean networked printing over port 9100 / jetdirect works fine. its the USB printing thats the issue
