Not sure but whatever it's doing it's printing wrong
12 POINT should, by definition, be 12/72 of an inch ALWAYS regardless
of DPI
But that's not how a lot of printing in RB is working when it comes
to printing on resolutions higher than 72 so you always end up
scaling text by resolution / 72
This is mentioned in the LR for PrinterSetup
something like
Dim p as PrinterSetup
p= New PrinterSetup
If p.PageSetupDialog then
g.TextSize = 12 * (p.VerticalResolution / 72 )
end if
(I think ... it may be MaxVerticalResolution)
but you do have to scale it yourself
