Hi,

I had same problem like you and i solved following step.

Settings -> Technical -> Parameters -> System Parameters -> find web.base.url and set value as http://0.0.0.0:[OdooPortNo] save and refresh page after try to print.

Thanks,

Hello Jeff Beidler,

There are two possiblites if your header is not appear in your report in odoo.

1) if wkthmltopdf lib not install in your system. (Install 0.11 or later version of wkhtmltopdf)

2) If you forgot call base template. (report.external_layout) inside your report template than you will not get header and footer in your report. Make sure you have follow this base structure for your report.

    <template id="your_unique_template_id">
            <t t-call="report.html_container">
                <t t-foreach="docs" t-as="var">
                    <t t-call="report.external_layout">  <!-- Make sure you have applied this template to your report. -->
                        <div class="page">

                                        <!-- Your report body-->

                       </div>

                 </t>
          </t>
      </t>
 </template>

Hope this will help.

Regards,

Anil.

hi, 

hear the problem was installation of wkhtmltopdf 

i have same issue in odoo 16 finally i corrected by proper installation of wkhtmltopdf

first we have to install wkhtmltopdf ubuntu 22 terminal

      1.    apt install wkhtmltopdf

      2. wkhtmltopdf --version 

      whether its 0.12.6 remove and download 0.12.5

      3.wget https://github\\.com/wkhtmltopdf/wkhtmltopdf/releases/download/0\\.12\\.5/wkhtmltox_0\\.12\\.5\\-1\\.bionic_amd64\\.deb

     \\ 4\\.sudo\\ dpkg\\ \\-i\\ \\ wkhtmltox_0\\.12\\.5\\-1\\.bionic_amd64\\.deb

sometimes\\ it\\ may\\ error\\ then\\ try\\ to\\ install\\ one\\ or\\ two\\ things 

    \\ 1\\.wget\\ http://archive\\.ubuntu\\.com/ubuntu/pool/main/o/openssl/libssl1\\.1_1\\.1\\.1\\-1ubuntu2\\.1\\~18\\.04\\.22_amd64\\.deb

   \\ 2\\.sudo\\ dpkg\\ \\-i\\ libssl1.1_1.1.1-1ubuntu2.1~18.04.22_amd64.deb

    3.sudo apt-get install xfonts-75dpi

    4.sudo apt-get update

    5.apt --fix-broken install

finally confirm  the "wkhtmltopdf version is  0.12.5"

open your report   from setting=>technical=>actions=>reports

in your report click on Other Information tab

you need to check "Add RML Header"  then the header will appear in PDF report
