Fix: You need the Kinamax TS9900 Printer Driver. Search for “Generic/Text Only” driver or visit the reseller’s website. For thermal printers, try TSC, Zebra, or Epson drivers (Kinamax often rebrands).
Some Kinamax TS9900 units use a cheaper CH340 chip. Get the official WCH.CN driver:
Solution: Change the COM port number.
Community-Packed Drivers (e.g., "DriverPack" or "Snappy Driver Installer Origin"): Some users find success with these, but only download from official, trusted repositories (like SDIO on GitHub). Use with caution – disable automatic driver installation of all hardware.
Alternative Open Source Drivers:
Even with a free new driver, problems can arise. Here’s how to fix them:
| Issue | Solution |
|-------|----------|
| “Driver not signed” error | Boot into “Disable driver signature enforcement” permanently via bcdedit /set testsigning on (admin CMD). |
| Device shows as “Unknown USB Device” | Unplug, uninstall the generic driver via Device Manager, then reinstall the Kinamax driver. |
| Driver installs but software crashes | Run the companion scope software in Windows 7 Compatibility Mode. |
| No data reading | Try a different USB port (preferably USB 2.0, not 3.0). Also replace the USB cable. | kinamax ts9900 driver download free new
