Prints single sided when duplex selected on Brother HL-5250DN printer. Connection is by USB. Used to work (i.e. printed double sided) till approx 1 month ago. Using Lucid Desktop 32bit (same happens on Lucid Desktop 64bit) fully up to date. I have attached a sample spool file from /var/spool/cups and cups error log.
