Hello (head hanging low),

I'm not sure if answering my own question indicates that I'm
clever or slow.  I don't think I want to know.

The correct way to control the size of graphics for the printer
(and the clipboard) is to control the dimensions and location of
the View that is being rendered.

r = dialog_printersetup(myprinterobject)
if r = 1 then begin

    myview->getproperty, location = wloc, dimensions = wdim
    myprinterobject->getproperty, dimensions = pdim
        ;to get a square plot... choose the smaller of pdim
        ;reduce its size a bit to get a decent margin
    viewdim = min(pdim) *0.8
        ;position the graphic by controlling the LOCATION
    myview->setproperty, dimension = viewdim, location =
pdim*0.1
    myprinterobject->newpage
    myprinterobject->draw, myview
    myprinterobject->newdocument
        ;restore the original view dimensions
    myview->setproperty, location = wloc, dimensions = wdim
endif


So, it does seem to be a  analogous to the controlling the
direct graphics device PRINTER.

Phew!  Now, if I could just find that pointer I lost...
