-This module allows users to send reports to a printer attached to the
-server.
+This module provides the core framework to send Odoo reports directly to
+printers. It defines the base models, configuration options and printing
+workflow, without depending on a specific printing protocol.
 
-It adds an optional behaviour on reports to send it directly to a
-printer.
+The actual connection with printers is delegated to extension modules
+(e.g. base_report_to_printer_cups), which implement support for a given
+printing backend.
 
-- Send to Client is the default behaviour providing you a downloadable
-  PDF
-- Send to Printer prints the report on selected printer
+Key features:
 
-It detects trays on printers installation plus permits to select the
-paper source on which you want to print directly.
+Flexible report output behavior:
 
-Report behaviour is defined by settings.
+Send to Client (default): generates a downloadable PDF.
 
-You will find this option on default user config, on default report
-config and on specific config per user per report.
+Send to Printer: sends the report directly to a configured printer (via
+backend module).
 
-This allows you to dedicate a specific paper source for example for
-preprinted paper such as payment slip.
+Support for user-level, report-level, and combined user/report printing
+rules.
 
-Settings can be configured:
+Extensible design: new modules can add support for additional printing
+systems or protocols.
 
-- globally
-- per user
-- per report
-- per user and report
+This modular approach allows administrators to configure printing
+globally, per user, per report, or per user/report combination, while
+keeping the printing backend independent and replaceable.

 Installation
 ============
 
-To install this module, you need to:
 
-1. Install PyCups - https://pypi.python.org/pypi/pycups
-
-.. code:: bash
-
-   sudo apt-get install cups
-   sudo apt-get install libcups2-dev
-   sudo apt-get install python3-dev
-   sudo pip install pycups
 
 Configuration
 =============
 
-To configure this module, you need to:
+Configuration Guide
+
+To configure and start using the Base Report to Printer module, follow
+these steps:
+
+1. User Access Rights
+
+Go to Settings → Users & Companies → Users.
+
+Open the user form and in the Access Rights tab, enable:
+
+Printing / Print User → grants access to the printing menu and
+user-specific printing preferences.
+
+2. Global Printing Settings
+
+Navigate to Settings → Technical → Printing → Printing Settings.
+
+Define the default printing behavior for reports:
+
+Send to Client (default): generates a downloadable PDF.
+
+Send to Printer: sends the report directly to a configured printer
+(requires a backend module such as base_report_to_printer_cups).
+
+3. User Preferences
+
+Each user can configure their own printing behavior:
+
+Go to Preferences (top-right menu, click on your name).
+
+In the Printing section, choose:
+
+Default action (Send to Client / Send to Printer).
+
+Preferred printer (if a backend module is installed and printers are
+detected).
+
+4. Report-Specific Configuration
+
+Go to Settings → Technical → Reports → Reports.
+
+For each report, you can define:
 
-1. Enable the "Printing / Print User" option under access rights to give
-   users the ability to view the print menu.
+Default printing action.
 
-The jobs will be sent to the printer with a name matching the
-print_report_name of the report (truncated at 80 characters). By default
-this will not be displayed by CUPS web interface or in Odoo. To see this
-information, you need to change the configuration of your CUPS server
-and set the JobPrivateValue directive to "none" (or some other list of
-values which does not include "job-name") , and reload the server. See
-cupsd.conf(5)
-<`https://www.cups.org/doc/man-cupsd.conf.html\\> <https://www.cups.org/doc/man-cupsd.conf.html\>>`__
-for details.
+Default printer (if available).
+
+These settings can be overridden at the user level.
+
+5. Per User & Report Combination
+
+Navigate to Settings → Technical → Printing → Report Configurations.
+
+Here you can assign specific rules combining:
+
+A user.
+
+A report.
+
+A printing action (Send to Client / Send to Printer).
+
+A printer and tray (if supported by the backend).
+
+6. Installing a Backend (e.g., CUPS)
+
+The base module does not include any printing backend. To connect with
+actual printers you must install an extension module, such as:
+
+base_report_to_printer_cups → adds support for CUPS printers, trays, and
+job management.
+
+Once installed, printers from the backend will be available in the
+configuration menus above.
 
 Usage
 =====
 
-Guidelines for use:
+Usage
+=====
 
-   - To update the CUPS printers in *Settings > Printing > Update
-     Printers from CUPS*
-   - To print a report on a specific printer or tray, you can change
-     these in *Settings > Printing > Reports* to define default
-     behaviour.
-   - To print a report on a specific printer and/or tray for a user, you
-     can change these in *Settings > Printing > Reports* in *Specific
-     actions per user*
-   - Users may also select a default action, printer or tray in their
-     preferences.
+Guidelines for use:
 
-When no tray is configured for a report and a user, the default tray
-setup on the CUPS server is used.
+- To use a specific printing backend (e.g. CUPS), make sure the
+  corresponding module (such as ``base_report_to_printer_cups``) is
+  installed and configured.
+- To print a report on a specific printer or tray, you can configure
+  defaults in *Settings > Printing > Reports*.
+- To define user-specific behaviour, go to *Settings > Printing >
+  Reports* and configure *Specific actions per user*.
+- Each user can also select a default action, printer or tray in their
+  *Preferences*.
+- When no tray is configured for a report or a user, the default tray
+  defined by the printing backend (e.g. the CUPS server) will be used.
+
+Notes
+-----
+
+- This module (``base_report_to_printer``) only provides the **base
+  framework**.
+- To connect with a real print system, you must install an additional
+  backend module (e.g. ``base_report_to_printer_cups`` for CUPS).
+- Other backend modules can be developed to support different print
+  protocols or environments.
 
 Known issues / Roadmap
 ======================
 
-- With threaded printing there's no download fallback when the issue
-  isn't detected by the CUPS Odoo backend. To able to do it, we would
-  need to notify the bus or use web_notify for it.
+
 
 Changelog
 =========
 
+18.0.1.0.0 (2025-10-15)
+-----------------------
+
+- [REFAC] Extracted all CUPS-specific functionality into a dedicated
+  module: ``base_report_to_printer_cups``.
+- [ADD] Introduced a base abstraction layer for report-to-printer, to
+  allow adding new backends (protocols) without modifying the core
+  module.
+- [IMP] Improved configuration instructions (global, per-user,
+  per-report, and per user+report).
+- [CLEAN] Updated documentation and module description to reflect new
+  architecture.
+- 
+
