Hi,

<?xml version="1.0" encoding="UTF-8"?>

<templates id="template" xml:space="preserve">

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

       <xpath expr="//div[hasclass('pos-receipt-contact')]" position="replace">

</xpath>

</t>

</template>

Please refer the above code. 
POS receipt’s corresponding template is ‘OrderReceipt’. First of all, An XML file is added inside the static>src>xml folder, and adds the above XML code into that XML file.
In this XML code, first, you have to inherit the OrderReceipt template from pos by using t-inherit-mode=” extension” and owl=”1”.The owl=”1”, which denotes it is an owl template. Then you have to extend the corresponding class. In the XPath expression, you can mention the exact path of the field which you want to delete. And give the position as ‘replace’. Close the Xpath tag.
The qweb template is added in the assets section of ‘web.assets_qweb’ in the __manifest__.py file.

Regards
