Brother, I appreciate that you at least made an attempt at providing Linux installation files, even going so far as to provide .DEB and .RPM files.
However, none of the solutions works, and even on my version of Linux, Ubuntu 10.04, probably the most common one around, the .DEB files did next to nothing. They didn’t setup Ubuntu’s printer configuration so that the printer showed, nor did they enable the drivers to be found when I tried to install the printer manually. (The Brother HL-2270DW is apparently so new that Ubuntu doesn’t have any default drivers in its repositories.)
What did work? Selecting HL-2170W from the default drivers list in Ubuntu. Seems to work fine! :P
