Item Number Truncating on Receipt

Aloha,

Apologies if this has been asked and answered. 

We have an issue with 13 digit Item Numbers being truncated on a 40 column receipt print. The receipt only prints the first 12 numbers.

I tried editing the receipt xml file on a POS register, this section in particular:

<<<<begin pasted text<<<<<<<

 =============================

   Transaction Details

   =============================

-->

      <IF>

         <CONDITION> Transaction.Type &lt;&gt; transactionDrop &amp; Transaction.Type &lt;&gt; transactionPayout &amp;  Transaction.Type &lt;&gt; transactionNoSale &amp; Transaction.Type &lt;&gt; transactionAccountPayment </CONDITION>

         <THEN>

            <TABLE>

               <FONT>      "Small"     </FONT>

               <BORDER>    tbNone      </BORDER>

               <COLUMNHEADER>

                  <ALIGNMENT>    "&lt;~"           </ALIGNMENT>

                  <WIDTH>        PageWidth * 0.20  </WIDTH>

                  <TEXT>         "Item"            </TEXT>

               </COLUMNHEADER>

               <COLUMNHEADER>

                  <ALIGNMENT>    "&lt;"           </ALIGNMENT>

                  <WIDTH>        PageWidth * 0.52  </WIDTH>

                  <TEXT>         "Description"     </TEXT>

               </COLUMNHEADER>

               <COLUMNHEADER>

                  <ALIGNMENT>    "&gt;~"           </ALIGNMENT>

                  <WIDTH>        PageWidth * 0.28  </WIDTH>

                  <TEXT>         "Amount"          </TEXT>

>>>end pasted text>>>

I decreased the PageWidth for the Description by 3 and increased the PageWidth for the Item by 3. There was no change in the output.

This is in RMS 2.0 on a HP (Cognitive) A799 printer, using OPOS drivers. 

Am I missing a step or looking in the wrong place? Any assistance is greatly appreciated!
