Am i missing something or is this what you are asking for

@media print {
input#DisplayAttachments {
display: none;
}
#dontprintme{display:none}
}
<div id='dontprintme'>
<div class="dhtmlgoodies_question">Notes and Comments </div>
<div class="dhtmlgoodies_answer">
      <div><table width="700" border="0" cellspacing="1" cellpadding="1">
</div>

or better way

@media print {
input#DisplayAttachments , #dontprintme {
display: none;
}

<div id='dontprintme'>
<div class="dhtmlgoodies_question">Notes and Comments </div>
<div class="dhtmlgoodies_answer">
      <div><table width="700" border="0" cellspacing="1" cellpadding="1">
</div>

You are probably making the same mistake most new programmers do -- thinking if you hide the DIV that you have incorrectly wrapped around the table structure, it will hide the table.  This is flawed thinking.

1.  first, tables need no enclosing DIV and should not have one because of erroneous inferences that the DIV properties somehow control the table state.  They do NOT.
2.  Remove the DIV, as it is doing nothing but confusing you.
3.  Give the TABLE an ID or NAME, and use CSS to hide it DIRECTLY, not trying to via the DIV.
4.  use the display:none and display:block on the TABLE, just as you would on other HTML elements

WHen you get the DIV out of the way and hide the table directly, it will work fine.  IF not, it won't work.
