Defining paper formats
At this point, our report looks good in HTML, but it doesn't print out nicely on a PDF page. We might get some better results using a landscape page. So we need to add this paper format.
At the top of the XML file, add this record:
<record id="paperformat_euro_landscape"
model="report.paperformat">
<field name="name">European A4 Landscape</field>
<field name="default" eval="True" />
<field name="format">A4</field>
<field name="page_height">0</field>
<field name="page_width">0</field>
<field name="orientation">Landscape</field>
<field name="margin_top">40</field>
<field name="margin_bottom">23</field>
<field name="margin_left">7</field>
<field name="margin_right">7</field>
<field name="header_line" eval="False" />
<field name="header_spacing">35</field>
<field name="dpi">90</field...
