Hi,

Try this code

<t t-call="web.html_container">
    <t t-if="not o" t-set="o" t-value="docs"/>
    <t t-set="company" t-value="company_id"/>
    <div class="header">
        <div style="border-top: 1px solid black;">
<img t-if="o.company_id.logo" t-att-src="image_data_uri(o.company_id.logo)" alt="Company Logo"
                 class="float-left"/>
<div style="font-size:14px;text-align:right;" class="float-right">
