I'm an Ubuntu user and I once created a tutorial on how to install the MFC210c.
While this is not directly related to "installing" a Brother MFC printer on an Ubuntu box, I suggest adding the following link directly in the tutorial as a courtesy service for MFC users.
This link points to a blog that Brother printer users would find indispensable when our cartridges run out of ink (apparently).
Half-way through a project where time was of the essence, the printer suddenly declared there was no black ink.
The cartridge had more than enough ink to complete the job. There wasn't time to run off to the store to replace it. The link provided above helped get the job done. The final required pages printed beautifully.
Do not throw out "almost finished" cartridges. Save yourself time and money.
