If you are trying to use this printer within barcode software, you may need a Driver Service Pack (DSP) rather than just a standard Windows driver.

Before installing the software, ensure the printer is plugged in, loaded with thermal paper, and connected to your computer via USB, Serial, or Ethernet. Turn the power switch . Step 2: Run the Driver Installer

Do not confuse drivers with firmware. Firmware is the internal software on the printer itself. Drivers are on your PC. Update both for best performance.
