another quick fix is to just select
Printer Properties
Make and Model [select change]
then check it on Brother then click [forward]
select this *second* driver option on right hand side "Brother HL-2140 Foomatic/hpijs-pcl5e [en]" then click [Forward]
click [apply] on next screen and your good to go
worked on both my Mint 11 laptops
*Edit* just checked the printer settings on my old Mint 8 Server .. whatada know same driver "Brother HL-2140 Foomatic/hpijs-pcl5e [en]" used on that one too should have checked that first wouldl have saved me 30 minutes of dicking around to find out the issue.
note I didn't install anything else other than plugging in the printer and letting Linux auto configure it, under Mint 10 it worked flawlessly but I had to manually change it to the above for it to work under Mint 11,
