Think of the ability of paper to hold/release the toner as a variable. It ranges for don't work because the toner will not release to don't work because the toner does not stay put long enough to transfer it.
On the too sticky end you have copier paper where the toner goes into the paper and traps fibers.
On the too slick end you have cooking parchment and alu foil.
If you graph the variable with X as the stickiness and Y as the ability to do a transfer you end up with a curve with a usable region on the top section of the graph.
Clay coated magazine paper is nearer the too sticky end of the usable region. It is less effected by the oil. It may be that the clay absorbs the oil from finger prints as does cat littler on an driveway oil stain.
The Pulsar paper is coated with starch and is nearer the too slick end of the usable region. The additional slickness caused by the oil makes it too slick and finger prints will not hold toner.
