I enjoy my new printer. One minor issue is that I cannot get a good print out on the maximum 1200 x 600 dpi. However, for most of my needs 600 dpi works just fine. To resolve this problem I download some deb packages from brother here and here. Then as root I make the directory /usr/share/cups/model/ and install brhl2140l followed by cupswrapperHL2140. In my printer manager I now see a new printer listed as HL2140 and send a test page to it. In the set printer options I change the dpi to HQ1200 and send a test page to the printer. Now I have high DPI printing from my Brother HL-2140 on Debian. If you want a low end monochrome laser printer for Linux/Debian I highly recommend this model. I got mine for under $100 from NewEgg.
