Hi,

I've recently found out that there are indeed issues with custom fonts in Odoo 11 & 12. You can find the bug report at https://github.com/odoo/odoo/issues/27503
Right now directly calling custom fonts in QWeb reports (printed as a PDF) does not work. You can use a workaround though. If you first define the font in <style type="text/css"> you will be able to use your custom font within your report. An example:

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <template id="your_custom_report_document">
        <t t-call="web.basic_layout">

            <style type="text/css">

                @font-face {
                font-family: 'MonixRegular';
                src: local('MonixRegular'), local('MonixRegular'),
                url(/your_module/static/src/fonts/monix/Monix-Regular.otf) format('truetype');
                }

                .h1-title {
                  font-family: MonixRegular;
                }
            </style>
            <h1 class="h1-title">Your custom font</h1>
        </t>
    </template>


    <template id="your_custom_report">
        <t t-call="web.html_container">
            <t t-foreach="docs" t-as="doc">
                <t t-call="your_module.your_custom_report_document"/>
            </t>
        </t>
    </template>
</odoo>

Keep an eye out for the bug report, eventually a real fix should come.
