This module extends base_report_to_printer to send print jobs through the Odoo Bus (WebSocket) instead of a traditional print server like CUPS.
When a report is printed, the module encodes the rendered PDF in Base64 and sends a print_job message through the bus to the user configured on the printer. A client-side listener running as that user receives the payload and forwards it to the local printer.
Main features:
Table of contents
Create a printer record in Settings > Printing > Printers with the backend set to WebSocket.
Set the System Name to the name of the target printer as known by the client-side listener (e.g. MFC-L3750CDW). Leave it empty to use the default system printer.
Set the WebSocket User to the Odoo user that will run the odoo-print-client agent. Print jobs are delivered through the bus subscription of this user.
Assign the printer as the default globally, per user, or per report following the standard base_report_to_printer workflow.
Install and run the odoo-print-client agent on the machine connected to the printer
pip install odoo-print-client odoo-printer --url "https://odoo.example.com" --db "prod" --user "admin" --password "admin"
See odoo-print-client on PyPI <https://pypi.org/project/odoo-print-client/>_ for full configuration options.
Once configured, printing works transparently. When a user prints a report that is set to Send to Printer and the assigned printer uses the WebSocket backend, the module will:
Render the report as PDF.
Encode the PDF content in Base64.
Send a print_job message through the bus to the printer’s configured user with the following payload
{
"printer_name": "<system_name of the printer>",
"file_data": "<base64-encoded PDF>"
}
The recommended client-side agent is odoo-print-client <https://pypi.org/project/odoo-print-client/>_, which connects as the configured user and forwards jobs to the local printer.
