Comment 6 for bug 287889

That's a bug in the Plug 'n Print detection, it should not match the incorrect Brother HL-2170W Foomatic/pxlmono (recommended) driver for your Brother HL-2140 printer (as seen in the printingbuginfo of Sebastián).

Please add this as another driver known to work on openprinting.org by clicking "Edit this printer" on this page: http://openprinting.org/show_printer.cgi?recnum=Brother-HL-2140

Brother provides a native linux driver for this printer which is not included into Ubuntu, your printer should work when manually installing this driver.

If you want this native printer driver to be installed automatically in future versions of Ubuntu you should ask Brother to provide a distribution independent driver package as described here: http://www.linux-foundation.org/en/OpenPrinting/WritingAndPackagingPrinterDrivers, so automatic download of the printer driver becomes possible as already implemented by this specification: https://blueprints.launchpad.net/ubuntu/+spec/printerdriverautodownload since Ubuntu Intrepid.
