+
+This module allows users to send reports to a printer attached to the client.
+
+It adds an optional behaviour on reports to send it directly to a printer.
+
+* `Send to Client` is the default behaviour providing you a downloadable PDF
+* `Send to Printer` prints the report on selected printer
+
+Report behaviour is defined by settings.
+
+You will find this option on default user config, on default report
+config and on specific config per user per report.
+
+This allows you to dedicate a specific paper source for example for
+preprinted paper such as payment slip.
+
+Settings can be configured:
+
+* globally
+* per user
+* per report
+* per user and report

+Installation
+============
+
+To install this module, you need to:
+
+#. Install QZ Tray on client - https://qz.io/download/
+
+#. Install pyOpenSSL
+
+PyOpenSSL is required to sign messages sent to the clients QZ Tray (and prevent warnings).
+
+.. code-block:: bash
+
+   sudo pip3 install pyOpenSSL
+
+#. Generate a certificate
+
+Take care about "Common Name (e.g. server FQDN or YOUR name) []:" THIS ENTRY IS IMPORTANT,
+this should be your Odoo domain name, can be filled in wildcard format an example of this would be \*.my-odoo-domain.com
+
+.. code-block:: bash
+
+   openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3650-nodes
+
+#. Set key and certificate on Odoo
+
+Go to /Settings/Technical/Parameters/System Parameters and set:
+- a parameter called qz.certificate with the content of the certificate.
+- a parameter called qz.key with the content of the key.
+
+
+#. Install certificate on client QZ Tray.
+
+Open QZ Tray menu /Advanced/Site Manager and drag and drop cert.pem for your Odoo domain.
+
+Configuration
+=============
+
+To configure this module, you need to:
+
+#. Enable the "Printing / Print User" option under access
+   rights to give users the ability to view the print menu.
+
+
+The jobs will be sent to the printer installed locally with a name matching the QZ Tray Printer.
+
+Usage
+=====
+
+Guidelines for use:
+
+ * 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.
