In my shop, I want ti integrate odoo pos, I have Epson tm-t20 connected directly to pos machine (with RJ45).

the connection between a pos machine and printer work fine (because I still use my old software and I can printed a receipt)

I want to integrate Odoo Pos, so I have install it in a vps, I have install also hw_escpos, hw_proxy, hw_scanner, hw,scale.

But, In odoo Pos, I don't see any change, I always can't print a receipt!!!!

I read in odoo documentation that we can use a printer directly connected to pos machine.

Any help?
