This English quick guide is based on the Korean catalog. Confirm model-specific compatibility and installation details on the manufacturer’s official page.
Download DS620A driver
- Match the full model number on the device label, including suffixes.
- Check your operating-system version and architecture on the official support page.
- Cancel pending print jobs before replacing an existing driver.
- Follow the manufacturer’s instructions for power, USB, and network connections.
Model and driver source
This guide is for the 6-inch dye-sublimation thermal-transfer photo printer; usb 2.0 type b, not a scanner/copier or native ethernet/wi-fi printer model DNP DS620A. The download button opens the official DNP support page in this window. The manufacturer’s page is authoritative for the available driver packages and their current compatibility.
Operating-system and download checks
The Korean catalog lists these systems for checking: Windows 11 ONLY driver 2.0.1.2 is 64-bit and must not be installed on Windows 7/8/10. The separate Windows 7/8/10 driver 2.0.1.1 is 32/64-bit. This guide covers those verified Windows packages; a Mac firmware updater or a global OS filter does not establish a compatible Mac print driver. Check the DS620A region and package.. Select your exact operating system and version on the official page. If your version is not offered, do not install a package intended for a different system.
Connection and installation
- Confirm DS620A, exact Windows version and architecture, administrator access and approved matching paper/ribbon. Unzip the official package locally; do not use a mirror. Leave printer USB disconnected before installing the Windows 11 driver.
- Before installing the Windows 11 driver, uninstall the previous DNP driver package as directed by the official manual, especially after upgrading from Windows 10. Preserve necessary settings and cancel pending jobs first.
- For Windows 11 run DriverInstall.CMD from the official extracted package, approve the expected UAC and Windows Security dialogs, and finish the driver-package wizard.
- Then connect USB to the printer Type B connector and PC and turn the printer on. Confirm DP-DS620 under Settings, Bluetooth and devices, Printers and scanners, then restart the PC.
- For Windows 7/8/10 use the separate applicable package and its installer instructions. Restart as directed; do not substitute the Windows 11-only package.
- Match driver Paper Size to the installed ribbon and paper. Load ribbon in the correct direction, take up slack and close the mechanism. Do not touch the cutter or hot head. Native USB is distinct from a separate optional network print server.
Troubleshooting
If the device appears under Unspecified, first ensure the driver package is installed. The Windows 11 manual then directs removal of only the Dai Nippon Printing DP-DS620 unspecified device, USB disconnection, PC restart and USB reconnection with printer power on; confirm DP-DS620 and restart after installation. For paper-size errors match the driver size to loaded ribbon/paper; reload incorrectly fitted ribbon. Cooling head normally clears automatically: wait. Follow the user-guide jam procedure without forcing paper or touching sharp/hot parts. Persistent System error after restarting printer and PC requires official service.
