I tried Chaosmonk's suggestion of using system-config-printer to set up my
printer and it offered "Generic PCL 6/PCL XL Printer Foomatic/pxlcolor
(recommended)" which apparently prints as well as the similar model's
gutenprint driver.
I called the command with "sudo" from a terminal such as gnome-terminal
sudo system-config-printer
Apparently for the Brother HL-L2370D printer, a generic driver is good
enough. Mine is a black and white printer that printed with no issues. As far
as other features such check ink/toner levels, that might be a reason to use
another driver.
