Custom print button, can't use load record function.

I am trying to add a custom print button to a transfer order so we can have complete control over what gets printed. However, whenever I use the nlapiLoadRecord() function, everything stops working.

I have one script that adds the button to the form

function button(type, form, req)
{

var id = nlapiGetRecordId();

var script = "print1(" + id +");"

form.setScript('customscript_print_trans')
form.addButton("custpage_button", "Print", script)

}

and the script that is supposed to print the html

function print1(id){

document.write("hello ")
record = nlapiLoadRecord('transferorder', id)
document.write("world")

}

When I press the button, I get a blank page with the word "hello " on it. It never gets to the world part. It also will not trigger alerts after the load record. I need to do this because I need to acces item line level information to print. I have also tried to pass the record from the button script to the print script which results in nothing being printed at all.
