I don't know the answers to most of the questions here . . . I just thought this printer should be in the list, if only to say "unsupported"

Brother publishes proprietary Linux drivers for CUPS and LPD for most of their laser printers and multi-function devices, including SANE drivers for the scanners. They can be downloaded free of charge on their Linux driver page.

Consumables/Refills: toner

User Notes

the brother 720 driver seems to work for 4560 and might be tried for 4550

For Debian install with Ubuntu: I use a MFC-8300 driver and get satisfactory results.
