So, the official word from Brother product managers is as follows. The short, over-simplified version is, they think it's a problem in the Ubuntu PrintManager and have no plans to change anything for my printer at least. Newer ones will probably not show the bug as they will use a simpler string.

From what they describe, it does sound like the Ubuntu PrintManager needs a tweak on how it deals with long strings.

The specification of the MIB is defined Max 255 strings and in the case of the 9840 we come close to using up the max string space. It would seem that the Unbuntu PrintManager should be able to handle at least 255 bytes.

There are no plans to change the MFC-9840CDW to this new format.
