If the driver still fails, visit the manufacturer’s support forum or contact their tech support with this info:
| Issue | Solution | |-------|----------| | Printer detected as “Unknown device” | Install USB-to-serial driver (if using serial cable) | | Prints gibberish or cut-off text | Change driver to Generic / Text Only | | No paper out sensor error | Use Epson TM-T88V driver (compatible with many ESC/POS printers) | | Not working with POS software (e.g., Loyverse) | Use OPOS driver + set printer as “ESC/POS” in app settings |
Not always. But if you move to a new POS software (e.g., from old cash register app to Loyverse), update to ensure full command support.
