Hello, I'm trying to print the receipt from the Point of Sale module to an EPSON TM U220D printer, but it prints many symbols and question marks. If I print from another application, like LibreOffice Write it prints fine. I downloaded the printer driver from epson https://download.epson-biz.com/modules/pos/index.php?page=prod&pcat=5&scat=32&pid=42 and installed too. I configure the margins on Firefox and nothing, always de symbols. Any help? 

I'm using Ubuntu server 14.04 LTS and Odoo version 8.

Thanks
