        pdf_file.write(pdf_content)

    print(f"Invoice PDF saved to {output_path}")

else:

    print("Invoice not found!")

in v17, the call :

pdf_file_url = models.execute_kw(db, uid, password, 'account.move.send', 'action_send_and_print', [4, [invoice_id]])

returns :

<Fault 2: 'Record does not exist or has been deleted.\n(Record: account.move.send(4,), User: 6)'>

What do ye have to do for the PDF to be generated ?

Hi,

There is already a default function to print the invoice from the action menu. Please check it whether it meets your need
open any invoice -> Action button -> print -> invoices

Hope it helps

Try this code to download an invoice file in PDF in Odoo 17 using Python.

# Import necessary modules from Flask framework and other libraries
from flask import Flask, request, jsonify, send_file
import xmlrpc.client
import requests

# Set up credentials and URL for Odoo instance
url = 'https://your_odoo_instance_url.com'
db = 'your_odoo_database'
username = 'your_odoo_username'
password = 'your_odoo_password'

# Authenticate and get session ID from Odoo
session_url = f'{url}web/session/authenticate'
data = {
    'jsonrpc': '2.0',
    'method': 'call',
    'params': {
        "service": "common",
        "method": "login",
        'db': db,
        'login': username,
        'password': password,
    }
}
session_response = requests.post(session_url, json=data)
session_data = session_response.json()
session_id = session_response.cookies['session_id']

# Set up XML-RPC connection to Odoo
common = xmlrpc.client.ServerProxy('{}/xmlrpc/2/common'.format(url))
uid = common.authenticate(db, username, password, {})
models = xmlrpc.client.ServerProxy('{}/xmlrpc/2/object'.format(url))

# Specify the ID of the invoice to retrieve
invoice_id = 21566

# Retrieve information about the specified invoice from Odoo
invoice = models.execute_kw(db, uid, password, 'account.move', 'read', [invoice_id], {'fields': ['name']})

# Trigger the action to send and print the invoice, and retrieve the URL of the generated PDF
pdf_file_url = models.execute_kw(db, uid, password, 'account.move.send', 'action_send_and_print', [4, [invoice_id]])

# Set up headers with the session ID for downloading the PDF
headers = {'Cookie': f'session_id={session_id}'}
download_url = f'{url}{pdf_file_url["url"]}'

# Download the PDF content of the invoice
response = requests.get(download_url, headers=headers)
pdf_content = response.content

# Specify the filename for the downloaded PDF based on the invoice name
filename = '{}.pdf'.format(invoice[0]['name'])

# Save the PDF content to a file
with open(filename, 'wb') as f:
    f.write(pdf_content)

Let me know if this works. It worked for me.

Hello,

I tried this script in odoo 17, but I have this error :

AttributeError: type object 'account.move' has no attribute 'invoice_print'

Do I need something else to make it work ?

Best regards
