Self-signed certificate for ePOS printers
|
||
|
|
=========================================
|
||
|
|
|
||
|
|
ePos printers are designed specifically to work with your Point of Sale system, which sends the
|
||
|
|
tickets directly to the printer.
|
||
|
|
|
||
|
|
Some models don't require an IoT box, but the connection between your web browser and the printer
|
||
|
|
may require a :doc:`secure connection with the HTTPS protocol <https>`. If so, a self-signed
|
||
|
|
certificate is necessary to use your printer.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|

Generate a Self-signed certificate
|
||
|
|
==================================
|
||
|
|
|
||
|
|
Access your ePOS printer's settings with your web browser by navigating to its IP address, for
|
||
|
|
example, `http://192.168.1.25`.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
- The printer automatically prints the IP address during startup.
|
||
|
|
- We recommend assigning a **fixed IP address** to the printer from the network router.
|
||
|
|
|
||
|
|
Go to :menuselection:`Authentication --> Certificate List` and create a new **Self-Signed
|
||
|
|
Certificate**.
|
||
|
|
|
||
|
|
- **Common Name**: the IP address of the ePos Printer, for example, `192.168.1.25`
|
||
|
|
- **Validity Period**: `10`
|
||
|
|
|
||
|
|
Create and reboot the printer, go to :menuselection:`Security --> SSL/TLS`, and check if
|
||
|
|
**Selfsigned Certificate** is selected.
|
||
|
|
|
||
|
|
Export the Self-signed certificate
|
||
|
|
==================================
|
||
|
|
|
||
|
|
To avoid having to accept the self-signed certificate several times, you can export it and then
|
||
|
|
import it to your web browser or mobile device.
|
||
|
|
|
||
|
|
To do so, access your ePOS printer's settings with your web browser by navigating to its IP address,
|
||
|
|
for example, `https://192.168.1.25`. Then, accept the self-signed certificate.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
Note that the protocol is now **HTTPS**.
|
||
|
|
|
||
|
|
Click on :menuselection:`Not secure --> Certificate is not valid`.

Import the Self-signed certificate to your browser (Chrome)
|
||
|
|
===========================================================
|
||
|
|
|
||
|
|
In your Chrome browser, go to :menuselection:`Settings --> Privacy and security --> Security -->
|
||
|
|
Manage certificates`, then open the *Authorities* tab, click on **Import**, and select all
|
||
|
|
functionalities of the certificate.
|
||
|
|
|
||
|
|
.. tip::
|
||
|
|
You can directly access these settings by navigating to `chrome://settings/certificates`.
|
||
|
|
|
||
|
|
Import the Self-signed certificate to your Android device
|
||
|
|
=========================================================
|
||
|
|
|
||
|
|
On your Android device, open the settings and search for *certificate*. Then, click on **Certificate
|
||
|
|
AC** (Install from device storage), and select the certificate.
