    Configuring Pisa for Django shouldn’t be too hard.

    There are really several examples on the net that show you how to do it and explain how to link to external resources in your templates:

    http://www.20seven.org/journal/2008/11/pdf-generation-with-pisa-in-django.html

    options = {
    'page-size': 'A4',
    'margin-top': '0mm',
    'margin-right': '0mm',
    'margin-bottom': '0mm',
    'margin-left': '0mm',
    'encoding': 'UTF-8'
}

pdfkit.from_file('input.html', 'output.pdf', options=options)

    Make sure to replace ‘input.html’ with the path to your HTML file, and ‘output.pdf’ with the desired path for the resulting PDF file.

    Note: Ensure that the wkhtmltopdf executable is in the system’s PATH or provide its path explicitly using the configuration parameter of pdfkit.

    I tried pdfkit, html2pdf and htmltopdf, But I couldn’t able to convert html to pdf. I found weasyprint module it works for me.

    it required weasyprint to be installed. The install can be downloaded from here. HTML and CSS that can export to PDF.

    install required Modules/packages

    pip install weasyprint

    Import required Modules

    from weasyprint import HTML
HTML("c:/xyz/out_case.html").write_pdf("c:/xyz/sample_out.pdf")
