We are currently running Sunmi D3 Pro Android POS units with Epson TM-M30iii network printers.

We are using the EPOS functionality to send receipts to the IP address of each Epson printer. While this works it is painfully slow - taking up to 18 seconds to print a receipt.

Are there anyways to improve this print time? The Sunmi units are equipped with USB ports so I could attach each printer to the Sunmi unit via USB. But this doesn't seem to work without downloading the receipt first which is not practical.

We are using Odoo 18 Community Edition.

Any suggestions will be greatfully received!
