Batch Conversion of PDF to Postscript

Question

I've been trying write a script for Batch conversion of PDF to PS files, using "silent" printing. I'm apparently missing something, because acrobat keeps crashing after executing the script (and the .ps files are not being created). Its also still prompting me for a filename. Not really sure of the syntax for keeping the same filename? I'm new to java script, so I'm sure its something I have wrong. My code is below, if anyone can help me out. I'm using Acrobat 7.0.9
this.print ({bUI: false,bSilent: true,bShrinktoFit: true,});
var pp = this.getPrintParams();
pp.interactive = pp.constants.interactionLevel.automatic;
pp.printername = "Xerox Docuprint 92C NPS PS2 C1";
pp.filename = "c:\temp\$filename$.ps";
this.print(pp);
Thanks

Why are you calling the print method twice?
Your syntax in the first call to print is in error. You have a comma after bShrinkToFit: true which is telling the JS interpreter to expect another argument.
Use this for filename (not the capital N in filename ... use proper case for property names):
pp.fileName = "/c/temp/" + this.documentFileName + ".ps";
Also, when printing to PostScript you shouldn't specify a printer name. Use this (again, note the proper case for properties):
pp.printerName = "";
It says exactly this in the documentation for the fileName property of the PrintParams object. I suggest you read the documentation relating to the methods you're trying to use ... always a good place to find answers.
> When printerName is an empty string and fileName is specified, the current document is saved as a PostScript file.
Although it may not consider C:\temp a "safe path" (I can't remember off the top of my head). You'll want to read the documentation regarding JavaScript "safe paths". If it is still prompting you for a filename it is most likely ignoring your path due to security restrictions.
