Is there a way, through Javascript or through other means, to set up a PDF using Acrobat so that it converts all text to black before printing?
 
I have a PDF with colored text in it that looks great on screen, but is failing to print effectively when sent to a black and white printer. Obviously, orange text is converting to grayscale and is too faint when printed. I'm hoping there is a way to modify the settings in the PDF so that if I send the PDF to someone who only has Adobe Reader, they can print it on a black and white printer and the text will print as black.
 
Any help is greatly appreciated.

You can use the print method of the Document object and specify in the PrintParams the color override. Your options are to let Acrobat decide, force color to grayscale or force color to monochrome.

Another option is to create a black and white layer with all of the contents of the PDF in black and white, and then create a WillPrint script that displays it, and a DidPrint script that hides it.

Thanks for the quick response!

"You can use the print method of the Document object and specify in the PrintParams the color override. Your options are to let Acrobat decide, force color to grayscale or force color to monochrome."

I think your first option should work great, but I have no idea how to accomplish it.

Is the above translated to javascript, or is it something I search for in the Acrobat preferences and menus?

I recommend looking in the Acrobat JavaScript Reference files, but here's the code to print the document in monochrome:

var pp = this.getPrintParams();
pp.colorOverride = pp.constants.colorOverrides.mono;
this.print(pp);
