Question

What are the necessary scripts functions or codes that needs to be called or included in order to print a document like receipts,reports and the like - just by clicking a print button. Here's a sample document that I wanted to print out - please click here Document to be printed.

If so, where should those scripts/codes to be place in the codes? Here is my codes:

    echo'<div class = "cust" style = "float:left;margin-left:20%;margin-top:1%;width:60%"><table>
<div style = "margin-left: 40%;">NEW BATCH MARKETING</div>
