Still me...
I know that the receipt in the POS is defined in the file /home/odoo/addons/point_of_sale/static/src/xml/pos.xml :
<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
..............................
.................................
<t t-name="PosTicket">
<div class="pos-sale-ticket">
<div class="pos-center-align"><t t-esc="new Date().toString(Date.CultureInfo.formatPatterns.shortDate + ' ' +
Date.CultureInfo.formatPatterns.longTime)"/> <t t-esc="order.get('name')"/></div>
<br />
<t t-esc="widget.pos.company.name"/><br />
PhoneSSSSSSSSS: <t t-esc="widget.pos.company.phone || ''"/><br />
User: <t t-esc="widget.pos.cashier ? widget.pos.cashier.name : widget.pos.user.name"/><br />
Shop: <t t-esc="widget.pos.shop.name"/><br />
<br />
<t t-if="widget.pos.config.receipt_header">
<div style='text-align:center'>
<t t-esc="widget.pos.config.receipt_header" />
</div>
<br
But it is the first time I see the templates (with the s at the end) xml tag.
How can I override or inherit only PosTicket from this last file in my own module?
Thanks
