This guide covers Epson Receipt Printers that are compatible with BETA and how to connect a cash drawer through an Epson receipt printer.
BETA currently integrates with Epson receipt printers (e.g., TM-m10 with Ethernet and similar models). Connecting your Cash Drawer to your EPSON printer, allows you to use a cash drawer with BETA.
epson / epson epson + <device serial number> / epsonSome EPSON printer models require HTTPS for browser communication. For BETA you should enable HTTPS properly so the printer is trusted by your browser and BETA can communicate securely. Follow these steps:
For a long-term solution, you must generate a self-signed certificate. Then, export and import it into your browser.
Step 01 | Understand the EPSON printer’s IP address
Ensure that the printer is powered on, and connected to the internet, via and ethernet (Please follow your EPSON printer model’s User's Guide, for more detailed instructions)
The Printer will print a receipt with information including the IP address, it should look something like this (e.g., https://192.121.1.22)
Step 02 | Generate a self-signed certificate on Windows 10
Navigate to the printer’s IP address (e.g., https://192.121.1.22) and force the connection by clicking:
Advanced
Proceed to [IP address] (unsafe)
Then, sign in using your printer credentials to access the printer settings. To sign in, enter epson in the ID field and your printer serial number in the Password field.
Click Certificate List in the Authentication section, and click create to generate a new Self-Signed Certificate. The Common Name should be automatically filled out. If not, fill it in with the printer IP address number. Select the years the certificate will be valid in the Validity Period field, click Create, and Reset or manually restart the printer.
The self-signed certificate is generated. Reload the page and click SSL/TLS in the Security section to ensure Selfsigned Certificate is correctly selected in the Server Certificate section.
Step 03 | Export a self-signed certificate on Windows 10
The export process is heavily dependent on the OS and the browser. Start by accessing your printer settings on your web browser by navigating to its IP address (e.g., https://192.121.1.22)
Then, force the connection as explained in the Generate a self-signed certificate tab (see above). The export process is heavily dependent on the OS and the browser.
Step 04 | Export a self-signed certificate on Windows 10
Start by accessing your EPSON printer settings on your web browser by navigating to its IP address (e.g., https://192.121.1.22). Then, force the connection as explained in the Generate a self-signed certificate tab.

The cash drawer connects directly to your EPSON receipt printer. This means the drawer can only be opened ("kicked") through the POS if it is plugged into the printer. If the drawer isn’t connected to the printer, the open command will not work, and the button on the POS will display.
BETA POS integrates with EPSON receipt printers to print out receipts. When the payment is initiated, a call is sent to the printer on the local network to print the receipt and kick the drawer.
Some printers do not allow communication over HTTPS/SSL. The TM-T88V, which is the RGP-recommended printer, is not the correct hardware.
To ensure communication can proceed over HTTP, open the Epson utility by navigating to the printer’s IP address. (username epson, password epson)
Navigate to Network > Security > SSL/TLS
Set Automatic Redirect HTTP to HTTPS to Disable and Send the changes to the printer.
Please note that the port in the BETA settings page may need to be set to 8043.
Another solution is to generate a self-signed certificate. Then, export and import it into your browser.
1) Generate a self-signed certificate
Navigate to the ePOS’ IP address (e.g., https://192.168.1.25) and force the connection by clicking Advanced and Proceed to [IP address] (unsafe).
Then, sign in using your printer credentials to access the ePOS printer settings. To sign in, enter epson in the ID field and your printer serial number in the Password field.
Click Certificate List in the Authentication section, and click create to generate a new Self-Signed Certificate. The Common Name should be automatically filled out. If not, fill it in with the printer IP address number. Select the years the certificate will be valid in the Validity Period field, click Create, and Reset or manually restart the printer. The printer utility may appear stuck after you click the “Create” button, try waiting a few minutes before trying again.
The self-signed certificate is generated. Reload the page and click SSL/TLS in the Security section to ensure Selfsigned Certificate is correctly selected in the Server Certificate section.
2) Export a self-signed certificate
The export process is heavily dependent on the OS and browser.
2.1) If you are using Google Chrome
Start by accessing your ePOS printer settings on your web browser by navigating to its IP address (e.g., https://192.168.1.25). Then, force the connection as explained in the Generate a self-signed certificate tab.
click Not secure next to the Address bar, and then open up Certificate is not valid;
go to the Details tab and click Export;
add .crt at the end of the file name to ensure it has the correct extension;
select Base64-encoded ASCII, single certificate, at the bottom of the pop-up window;
save, and the certificate is exported.
Make sure that the certificate ends with the extension .crt. Otherwise, some browsers might not see the file during the import process.
2.2) If you are using Firefox
Click the lock-shaped icon 
on the left of the address bar;
go to Connection not secure
‣ More information
‣ Security tab
‣ View certificate;
In the View certificate popup
- scroll down to the Miscellaneous section;
- click PEM (cert) in the Download section;
- save, and the certificate is exported.
2.3) Other Browser, note BETA suggests Google Chrome
If you need to export SSL certificates from an operating system or web browser that has not been mentioned, search for export SSL certificate + the name of your browser or operating system in your preferred search engine.
3) Import a self-signed certificate
The import process is heavily dependent on the OS and the browser.
3.1) Windows
Windows manages certificates, which means that self-signed certificates must be imported from the certification file rather than the browser. To do so:
Open the Windows File Explorer and locate the downloaded certification file;
right-click on the certification file and click Install Certificate;
select where to install the certificate and for whom - either for the Current User or all users (Local Machine). Then, click Next;
on the Certificate Store screen, tick Place all certificates in the following store, click Browse…, and select Trusted Root Certification Authorities;
click Finish, accept the pop-up security window;
restart the computer to make sure that the changes are applied.
3.2) Other Browser, note BETA suggests Google Chrome
Similarly, to import SSL certificates from an unmentioned OS or browser, search for import SSL certificate root authority + the name of your browser or operating system in your preferred search engine.
4) Check if the certificate was imported correctly
To confirm your printer’s connection is secure, connect to its IP address using HTTPS. For example, navigate to https://192.168.1.25 in your browser.
If the SSL certificate has been applied correctly, you should no longer see a warning page, and the address bar should display a padlock icon, indicating that the connection is secure.
