+A different receipt template is used if the PoS ticket is printed via web or
+via proxy. In the case the ticket is printed via web (through the browser) the
+company logo isn't printed. This module adds it.
+
+In other hand, company_logo is loaded using `/web/binary/company_logo`
+controller `that returns a 150px wide logo <https://github.com/odoo/odoo/blob/11.0/addons/point_of_sale/static/src/js/models.js#L481>`_:
+
+but after that logo is resized to 300px width, so a pixelled logo appears even
+original logo is 300px wide.
+That's why we override how company_logo is loaded. We also resized it to 260px
+(not 300px) wide because appears cut in PDF.
