Is this something that is just a configuration issue on my part?

Tracking down the 4x7 with Price label in  Views / report_simple_label2x7:

• ~ /web#id=864&menu_id=4&cids=1&action=29&model=ir.ui.view&view_type=form

Look for this line:

div t-out="barcode" t-options="{'widget': 'barcode', 'symbology': 'auto', 'img_style': barcode_size}"/>

Updated to:

div t-out="product.barcode" t-options="{'widget': 'barcode', 'symbology': 'auto', 'img_style': barcode_size}"/>


!-- Since barcode value writes lot number if exists, explicitly adding human readable barcode value --> 


span class="text-center" t-out="product.barcode"/>
br/>
span class="text-center" t-out="barcode"/>

Somewhere in the code it reuses "barcode" as the lot number if used, so there isn't an option to print both the barcode number and lot number  This changes that for this one label.  

Looking for a cleaner solution.

Upon further testing, doesn't work when combining products that require lot numbers and those without on the same PO.  The ones with lot numbers, barcodes print, but the barcode number is duplicated.
