Actually, my wording was wrong: the Brother drivers do not use gutenprint and gutenprint does not support the MFC7420, as far as I can read the source/doc.
I just can acknowledge that the printer stopped working after upgrading gutenprint to 5.2.11 (with a gutenprint-related error message), and that downgrading gutenprint solved the issue.
