How to print only the black text in fillable form if you have color in the background of the fields

Using these two scripts should be faster. The first must be placed in the "Document will print" event, the other must be placed in the "Document did print" event.

Don't forget to edit color values to match your green color.

// DOCUMENT WILL PRINT
var bSale = this.dirty;
for (var i=0; i<this.numFields; i++) {
var oFld = this.getField(this.getNthFieldName(i));
if (oFld.type == "text") {oFld.fillColor = color.white;}
}
this.dirty = bSale;

// DOCUMENT DID PRINT
var bSale = this.dirty;
for (var i=0; i<this.numFields; i++) {
var oFld = this.getField(this.getNthFieldName(i));
if (oFld.type == "text") {oFld.fillColor = ["RGB", 244/255, 249/255, 255/255];}
}
this.dirty = bSale;

Place the green backgrounds on a separate layer.

Set this layer as "visible but non printable".*

Use a transparent background for form fields.*

Then export to "Interactive PDF" with PDF layers.

* This can be done with Acrobat Pro too.
