Your thermal printer speaks RS-485. Your POS backend wants RS-422. Your modern PC has neither port. This Jaycar converter plugs into USB and auto-detects the serial signal rate, so you skip the COM-port headache entirely. No external power brick. Plug it in, it works. 300 bps up to 921 kbps over a USB 2.0 interface. Your printer's talking again before your next shift
