    pdf.output()
    
    return HttpResponse(pdf, content_type='application/pdf')

I'm view pdf on new tab but it's show me error.

Unfortunately, we do not know what your error is. But try to return the pdf file via binary stream (irrelevant part skipped):

import io
from django.http import FileResponse

    ...
    pdf.set_font('Arial', 'B', 16)
    pdf.cell(40, 10, 'Hello, World!')
    file_stream = io.BytesIO(pdf.output())
    return FileResponse(file_stream, as_attachment=False, filename="test.pdf")
