I'm trying to make the lines on my 4" x 6" packing slip thicker as it keeps getting stuck on my label printer and skipping the text below, but am not able to find how to change it. Specifically, the lines on the boxes around "Description" and "Qty", and the line below the items. I've attached a sample packing slip and circled in red the items I am attempting to change.
Order Items Header:
<th align=left style=width:0.75in class=sku>Item</th>
<th align=center style=width:0.35in>Qty</th>
<th align=center class=location_ssreserved>Location</th>
<td>[Item Title]<br>[Item Options]</td>
<td align="center"><span style="font-size:1.5em;font-weight:bold;">[Quantity]</span></td>
<td align=center class=location_ssreserved>[Product Location]</td>
Thanks in advance!
