The purpose of lubrication is to reduce wear and tear between moving parts. The decision to lubricate is arrived at by manufacturers recommendations. Visualizing your Dot Matrix, its a busy machine. The platen assembly should lubricated as there are moving parts. I have rarely seen a pulley being lubricated. Print head pins should not be lubricated it just doesn't sound right, paper advance bushings should not be lubricated as you are likely to transfer dirt to the paper being transferred.  Don't lubricate A, B and C. I have answered this just by visualizing the unit and the purpose its made for.
