A4 Print setup

[Dwayne Rothe]

Hi All,
Can anyone help me with page settings for printing? 
I want to be able to force the papersize for printing to A4. Are there specific commands for letter & A4 settings or do I need to 
use the printPaperSize property? If so what is the correct setting for A4? I know that letter size is 612, 792.
Also, am I correct in stating the default printMargins for A4 are 54,36,36,36 ?

 Cheers Dwayne.......
