where to change layout setup (mac)?

I opened an Igor file created in a PC. The layout setup is also remembered. Although it is straightforward to use the layout setup to set margins in PC, I did not find an option to do it in Mac (OS x, V10.5.8, Igor 6.22). Any suggestions?

I think the easiest way to do this is to use Igor's PrintSettings operation. To learn about it, execute:
DisplayHelpTopic "PrintSettings"


Mac OS X also allows you to create a custom paper size with custom margins. Choose File->Page Setup, choose Manage Custom Sizes from the Paper Size popup menu, and set paper size and margins in the resulting dialog.
