You must consider two things. First, PagePosition and Leftmargin depend
on the printer resolution (which you can query from the printer
properties); "500" means something to one printer, and something else to
another. Second, a combination of printer/printer driver can work
differently from another one. You could try to draw some line, with
different starting points, to see what happens and deduce margins and
behaviours.
The best I did about this, was to have parameters for scaling and
offsets. This way you setup your print in a straightforward manner, and
then you can adapt your page to any printer by varying few parameters
and a few tries.
