hello every one,

I buy an Epson TM-T20X M352A Ethernet, i tray to configure with Pos module i insert de Ip Adress when i tray to print receipt i receve in the screen this tow messages 

Fail to connect to printer

and the second one 

Please check if the printer is still connected. some browsers don't allow HTTP Calls from websites to devices in the network (for security reasons). if it is the case you will need to follow odoo's documentation for self signed certificates for ePOS printers and Secure connection HTTPS to solve the issue ensur you accept manually the certificat"

I tray with Google Chrom, Fierfox and Edge 

I generate Certificat from Epson netconfig and importe it 

Can you help me to start printing from Pos
