Hi,

Please ensure wkhtmltopdf has proper permissions to access the files and directories it needs. Run chmod +x /usr/local/bin/wkhtmltopdf to make it executable and verify the webkit_path points to the correct location of the installed wkhtmltopdf. You can check the path with which wkhtmltopdf.

Hi,
Can you try installing wkhtmltopdf 0.12.5 and see if it makes any difference ?
Thanks

Hello,

Are you able to solve the issue?

I have the same problem on m2 pro running macOS 15.2. 

Tried to install in rosetta mode and odoo prints wrong fonts, no fonts and blanks. I have tried the the webkit path, report.url in all different ways possible, nothing works. Sometimes it will print properly but mostly its completely wrong.

I have installed 0.12.6 and 0.12.5 all version of them as well

Has anyone found a solution to this?

The PDF rendering issue you are experiencing on MacOS when using Odoo might be related to the wkhtmltopdf configuration, font rendering, or compatibility with the macOS platform. Below are some steps and suggestions to resolve this issue:

Troubleshooting Steps:

1. Font Rendering Issue

• Ensure Fonts Are Installed Correctly:
  • Install any custom fonts required for the report on the MacOS system.
  • Check if the fonts used in the Odoo templates are supported by wkhtmltopdf.
• Embed Fonts in the Template:
  • Use CSS in your report templates to explicitly include or embed fonts.

  @font-face {
      font-family: 'CustomFont';
      src: url('path/to/font.woff') format('woff');
  }
  body {
      font-family: 'CustomFont', sans-serif;
  }
  

2. Verify wkhtmltopdf Configuration

• Install the Correct Version:
  • Use version 0.12.5 or 0.12.6 of wkhtmltopdf, which is known to work well with Odoo. Ensure it matches the architecture (ARM or Intel-based Mac).
• Set Path Correctly:
  • Confirm the path in odoo.conf:

    [options]
    webkit_path = /usr/local/bin/wkhtmltopdf
    

  • Restart Odoo after making changes:

    sudo service odoo restart
    

• Test Command-Line Rendering: Run wkhtmltopdf from the terminal to check if it produces consistent results:

  wkhtmltopdf http://example.com test.pdf
  

3. Update Report URL

• Add the following to odoo.conf:

  report.url = http://127.0.0.1:8069
  

• Restart Odoo to apply the changes.

4. Debug Rendering Behavior

• Open browser developer tools and inspect how the report appears in the browser before rendering.
• Check for any errors in Odoo's log file during report generation.

5. Verify CSS and Template Consistency

• Ensure consistent font and CSS usage in your report template.
• Sometimes, conflicting CSS rules can cause issues with PDF rendering.

Recommendations for Better Compatibility

Switch to a Different PDF Rendering Library

If wkhtmltopdf is unreliable, consider switching to an alternative library like WeasyPrint. You can install and configure it for Odoo as follows:

1. Install WeasyPrint:

   pip install weasyprint
   

2. Configure Odoo to Use WeasyPrint: Modify your report templates or write a custom module to use WeasyPrint instead of wkhtmltopdf.

Check for Odoo Updates or Patches

Verify if there are any updates or patches for your version of Odoo that address PDF generation issues.

Use a Virtual Environment

Run wkhtmltopdf in a virtualized Linux environment (e.g., Docker) to avoid Mac-specific issues.

Summary

This issue likely stems from font rendering or wkhtmltopdf inconsistencies on MacOS. Start by verifying the fonts, CSS, and wkhtmltopdf installation. If the problem persists, consider alternative solutions like WeasyPrint or using a virtualized environment.

If you need help with any of these steps, let me know!

I had the same problem, and clearing the browser cache resolved it. Try clearing your browser’s cache and then reload the page. On most browsers, you can do this by pressing Ctrl+Shift+Delete (or Cmd+Shift+Delete on macOS) and selecting the cache to clear.

Hi,

Has your problem been solved? 

If so, could you post the solution? I have a Mac M1 and I have the same problem with odoo V17.

Notice how it's different each time I print a pdf:
