Thank you!
For others to reference, the final script that works is:
// Description: This script adds a text field to the left side of all
// pages. It also sets a doc level JavaScript that executes when the
// document is printed and fills the field with date.
// Add field to each page of form
var inch = 72;
for (var p = 0; p < this.numPages; p++) {
// create rectangle quads for field
var aRect = this.getPageBox( {nPage: p} );
aRect[0] = 0.0;
aRect[1] = 0.0;
aRect[2] = 26.0;
aRect[3] = 792;
// now construct text field to fill with date information
var f = this.addField("PrintField", "text", p, aRect )
f.delay = true;
f.textSize = 16;
f.textFont = font.HelvB;
f.textColor = color.black;
f.alignment = "center";
f.readonly = true;
f.print = true;
f.hidden = true;
f.delay = false;
}
for (var p = 0; p < this.numPages; p++) {
// rotate the text
var f = this.getField("PrintField." + p)
f.rotation = 90;
}
// Adds a doc level script to populate text field when doc prints from
// Acrobat or the free Adobe Reader. Note: the '\r' character represents a
// carriage return.
var myWillPrintScript = 'var f = this.getField("PrintField"); \r' + 'f.hidden = false; \r' + 'var d = new Date(); \r' + 'var year = d.getYear()+1900; \r' + 'f.value = "THIS DOCUMENT ONLY EFFECTIVE ON " + (d.getMonth()+1) + "/" + d.getDate() + "/" + year; \r'
var myDidPrintScript = 'var f = this.getField("PrintField"); \r'
+ 'f.value = ""; \r'
+ 'f.hidden = true; \r'
// Now set the scripts to execute on the Will/Did Print events.
this.setAction("WillPrint", myWillPrintScript);
this.setAction("DidPrint", myDidPrintScript);
