You can use this script, this works fine to me, But you need instal pip install Weasyprint

def checkout_pdf(request, key):

from django.db.models import Sum

_queryset = CheckOut.objects.filter(id= key ).select_related('client').annotate(soma=Sum('checkoutitem__total_value')).all()
_company = SystemCustomization.objects.all().get()

from django.http import HttpResponse
from django.template.loader import render_to_string 
from weasyprint import HTML, CSS
import tempfile
from framework import settings

context= {'cli' : _queryset, 'company': _company}

 # Rendered
html_string = render_to_string('checkout-pdf.html', context) #choice your templae
html = HTML(string=html_string, base_url=request.build_absolute_uri())
result = html.write_pdf(stylesheets=[CSS(settings.STATIC_ROOT +  '/application/css/invoice.css')]) #choice your css to customize the html

# Creating http response
response = HttpResponse(content_type='application/pdf;')
response['Content-Disposition'] = 'attachment; filename=%s.pdf' % key #choice filename
response['Content-Transfer-Encoding'] = 'binary'
with tempfile.NamedTemporaryFile(delete=True) as output:
    output.write(result)
    output.flush()
    output = open(output.name, 'rb')
    response.write(output.read())

return response
