Thank you PeterPaul. Will try again after the next Bionic kernel upgrade. In the meantime the brother MFC is plugged into my 16.04 PC and network connected. The printer cost me $20 at a garage sale and only has USB. PS - more pieces of the puzzle: the brother-udev-rule-type1 DEB package mentioned above as not necessary creates a file /opt/brother/scanner/udev-rules/type1/NN-brother-mfp-type1.rules and this rules file has a comment that it should be copied to the relevant udev folder - /etc/udev/rules.d; The driver name is "Brother MFC7420 for CUPS" and does not have a hyphen after MFC so it appears after all MFC printers in the list of drivers and is easily missed
