I've been having a conversation with Brother about my HL-2030 laser
printer connected to AirPort Express printing occasional blank pages by
itself without my "consent". I never printed them but they still emerge on
the paper output tray once in a while (printer is upstairs). I've now
witnessed with my own ears (since I hear the printer going off) that after
opening X-Chat Aqua 0.15.2 my Brother HL-2030 starts printing by itself.
Any idea what's causing this? Polling of some printer port?
