# The cups binary is 64 bit. Until Brother releases source for the 32 bit lpr
# binary blobs, 64 bit users must enable multilib.

# This has not been tested with non cups lprng.

# NOTE 1: Remember to add user to lp group using
# gpasswd -a USER lp
# NOTE 2: Remember to logout after adding groups
# NOTE 3: Set each printer default Media Size to Letter with
# lpadmin -p BR5910 -o media=Letter
