I had this printer working fine under 12.04 using ubuntu recomended QL-500 foomatic driver. Since I upgraded to 16.04 it does not work anymore. When I send the print job, the led starts flashing red, and nothing prints. This is true with Brother drivers that I have tried as well.
I have tried this
brother ql570 labelprinter driver does not work
but nothing changes - my 32bit libraries are the latest available.
I have also tried this:
again no joy. However I have some error messages relating to virtualbox which I have installed.
Thank you for any help - I need my labels to deliver my bread to shops tomorrow.....
