title: How to link a custom paper format to a pdf report in Odoo 8?
body: <p>I want to print labels from odoo. For that I created a custom paper format and finding a way to link it to my label report. My label report is a pdf report. (When I create  the report I can view it in the default paper format.)</p>
  
  <p>this is the code for custom paper format</p>
  
  <pre><code>&lt;openerp&gt;
  &lt;data&gt;
      &lt;record id="mymodule_label" model="report.paperformat"&gt;
          &lt;field name="name"&gt;Item Label&lt;/field&gt;
          &lt;field name="default" eval="True"/&gt;
          &lt;field name="format"&gt;custom&lt;/field&gt;
          &lt;field name="page_height"&gt;50&lt;/field&gt;
          &lt;field name="page_width"&gt;100&lt;/field&gt;
          &lt;field name="orientation"&gt;Portrait&lt;/field&gt;
          &lt;field name="margin_top"&gt;3&lt;/field&gt;
          &lt;field name="margin_bottom"&gt;3&lt;/field&gt;
          &lt;field name="margin_left"&gt;3&lt;/field&gt;
          &lt;field name="margin_right"&gt;3&lt;/field&gt;
          &lt;field name="header_line" eval="False"/&gt;
          &lt;field name="header_spacing"&gt;3&lt;/field&gt;
          &lt;field name="dpi"&gt;80&lt;/field&gt;
      &lt;/record&gt;
  &lt;/data&gt;
  &lt;/openerp&gt;
  </code></pre>
