File for POS Receipt is point_of_sale/static/src/xml/Screens/ReceiptScreen/OrderReceipt.xml

Hi,

The POS receipt is located in point_of_sale/static/src/xml/Screens/ReceiptScreen/OrderReceipt.xml.

Inherit the template below to add a number to the order line and remove the tax field from the receipt.<templates id="template" xml:space="preserve">

    <t t-name="OrderReceipt" t-inherit="point_of_sale.OrderReceipt" t-inherit-mode="extension" owl="1">

</t>

<xpath expr="//div[hasclass('orderlines')]" position="after">

   //code here

</xpath>

</templates>

Hope it helps
