The owner of a selected control - a mystery

Not quite sure I understand this (I did once, but i’ve got rusty - oil can!). I assumed that the following code would exactly fill a page:

   set the printCardBorders to true
   set the printPaperSize to (the width of this card) & "," & (the height of this card)
   set the printMargins to "0,0,0,0" 
   print this card

But maybe you're saying that there is some hidden factor here. One thing I can think of in a physical bit of paper (which a PDF isn't, really) is that only certain printers can print to the very edge, so there might be a kind of hidden margin (is this "the available print area"?). I am not sure if the printPaperRect comes into this: as far as I can see, it shouldn't, since the printMargins are measured from the edge of the page according to the LC Dictionary. The printing might be cropped if edge-to-edge isn't available, but that should not increase the number of pages printed, should it?

I will experiment some more.

Remember when dealing with margins that the margins represent the amount of space around the rect of the card itself. If your fields or other controls are not at the very edges of the card, then they will be inset more than just the margin amounts.
