Thanks for your reply, but it is not yet clear to me.
I know you can set some print properties in the Apple Print event, such as copies, collating, target printer ...but how can I adress the printer-specific options, such as duplex printing? Could you give me a sample line of code?
And next step, how can I include this "Apple -print" setting in an InDesign Print preset using Applescript? I suppose I have to set the apple printer prefs before creating the InDesign preset. Right?
Thanks in advance,
