ISO of code that will allow gift notes to appear on a packing slip.

If you don't mind a bit of HTML copy/paste...

Settings > Templates > Packing Slips

Under Actions, click the 3 dots. You will need to work on a copy and give it a new name. That way if anything goes wrong, you can't lose your default. Also, this allows you to choose a different template when you go to print them based on whether you need a gift note or not.

This is the code we use. Your usage may vary, depending on which field your gift notes push to. Ours go to "Notes from Buyer." Under Order Footer, I have:

<table cellspacing=0 cellpadding="2" border="0" style="width:100%" class="footer">
<tbody>
<tr>
<td rowspan="4" class="notes">
</td>
<div>[Notes from Buyer]</div>
</tr>
</tbody>
</table>

By the way, under Order Header, Order Items Header, and Order Items you can also delete anything you don't want. For example, for our template that includes Notes from Buyer, we have deleted the codes that allow any prices to show on the packing slip. PLUS, you can download a sample before saving any changes.

Hey man 
I saw this reply of yours and it is really nice and helpful but I would like to ask something, I want the gift messages go halfway of the paper and if I have more than 1 order I don't want to print separate pages for each gift messages.
So lets say I have 4 orders that has 4 different gift messages right? I want all of them in one page like its divided to quarters! Do you know if we can do smt like that???
