BPN - With reference to modern notes the "P" is generally referencing the position number.
so BPN would be Back Position Number.
Unlike notes of the first several generations where each note had its own separate plate, the last few generations have one large plate that prints the whole sheet at the same time. In this case there is only one plate but each note in that plate has a position and that is what the position number denotes.
Several researchers have studied position numbers and print ordering of notes.
