self-signed certificate is no longer required. The recommended approach is to use the
:doc:`Local Network Access <pos_lna>` method instead.
To work with Odoo, some printer models that can be used without an
:doc:`IoT system </applications/general/iot>` may require the HTTPS protocol to establish a secure
connection between the browser and the printer. However, trying to reach the printer's IP address
using HTTPS leads to a warning page on most web browsers.

Generation, export, and import of self-signed certificates
==========================================================
Generate, export, and import self-signed certificates
=====================================================
For a long-term solution, you must generate a **self-signed certificate**. Then, export and import
it into your browser.
Printers that operate without an :doc:`IoT system </applications/general/iot>` still require secure
communication, which can be achieved by :ref:`generating <pos/epos-ssc/certificate-generation>`,
:ref:`exporting <pos/epos-ssc/certificate-export>`, and/or :ref:`importing
<pos/epos-ssc/certificate-import>` a self-signed certificate.
.. important::
**Generating** an SSL certificate should only be done **once**. If you create another
certificate, devices using the previous one will lose HTTPS access.
- Generating a self-signed certificate should only be done **once**. Creating another
certificate causes devices using the previous one to lose HTTPS access.
- Printers that use an :doc:`IoT system </applications/general/iot>` do not need a
self-signed certificate, as the IoT box generates it automatically.
- For stable results, it is strongly recommended to use the Google Chrome browser to generate
the self-signed certificate.
.. note::
To export self-signed certificates from an operating system or a web browser that is not
mentioned in this documentation, search for `export SSL certificate` and the name of your
browser or operating system in the preferred search engine. Similarly, to import self-signed
certificates, search for `import SSL certificate root authority` in the preferred search engine.

Self-signed certificate generation
----------------------------------
The generation process depends on the :abbr:`OS (Operating System)` and the browser.
.. tabs::
.. tab:: Windows 10 & Linux OS
.. group-tab:: Windows 10 & Linux
To generate a self-signed certificate on **Google Chrome**, follow the next steps:
#. Open the browser, type the printer's IP address in the search bar (e.g.,
`https://192.168.1.25`), and press `Enter`.
#. On the security warning page, click :guilabel:`Advanced`, then :guilabel:`Proceed to
[IP address] (unsafe)` to force the connection.
#. On the EPSON platform, click :guilabel:`Advanced Settings`, then :guilabel:`Administrator
Login` to log in to the printer's homepage.
#. Type the initial password located at the back of the printer in the :guilabel:`Current
Password` field, then press `Enter`.
#. Go to :menuselection:`Network Security --> SSL/TLS --> Certificate`.
#. On the :guilabel:`Certificate` page, click :guilabel:`Update` under the
:guilabel:`Self-signed Certificate` section.
#. Adapt the :guilabel:`Common Name` field to retain only the IP address, then click
:guilabel:`Next`, then :guilabel:`OK`. Wait for the printer's lights to stop blinking.

The Epson homepage may vary depending on the printer model used. For the Epson TM-m30 ii,
log in to the Epson homepage by typing `epson` as the username and the printer's serial

#. Enter a name for the certificate.
#. Select an identity type, then the type of certificate.
#. Click :guilabel:`Create`.
#. Review the certificate, then click :guilabel:`Done`.

correctly, you should no longer see a warning page, and the address bar should display a padlock
icon, indicating that the connection is secure.
Once the certificate is installed, authenticate it as follows:

===============================
To confirm the printer's connection is secure, connect to its IP address using HTTPS. For example,
navigate to `https://192.168.1.25` in a browser. If the self-signed certificate has been applied
correctly, no warning page appears, and the address bar should display a padlock icon, indicating a
secure connection.

ePOS printers are designed to work seamlessly with Point of Sale systems. Once connected, these
devices automatically share information, allowing for direct printing of tickets from the POS system
to the ePOS printer.
Receipt printers integrate with Point of Sale systems to receive print jobs directly from the POS.
Once properly configured and connected, this integration enables automatic receipt printing for
every completed transaction.

Epson printers are strongly recommended. The following printers are compatible with Odoo:
- Network-based printers that support the ePOS communication protocol (without IoT), such as
the TM-m30 iii (model 112 or 152).

=============
To use an ePos printer in Point of Sale:
To configure the printer, connect it to a power source, then to the network using either Wi-Fi or
an Ethernet cable. Then, power the printer on; an automatic ticket with the printer’s IP address
gets printed upon connection. Keep it for the configuration process.

When the printer connects to a network, it automatically prints a ticket with its IP address.

Troubleshooting
===============
To resolve common hardware issues, including connectivity failures, configuration errors, and
physical maintenance, follow the instructions below:
- Check the printer's blinking lights to help identify the source of a problem.
- If the printer does not print the first automatic ticket with the IP address, check the network
cable or Wi-Fi connection.
- If the receipt comes out blank, the paper roll may be upside down; try flipping it.
- If the POS cannot connect to the printer, make sure the printer's IP address entered in Odoo
matches the one on the first automatically printed ticket. Also, ensure the router assigns the
printer a static IP address.
