Okidata ML690 Driver

The Okidata ML690 driver helps Windows communicate with your ML690 dot-matrix printer so applications can send print jobs using the appropriate device settings. It is useful when setting up the printer for the first time, reconnecting it after a Windows reinstall, or troubleshooting printing problems on a local or configured network connection.

Key Features

• Printer communication: Provides the software interface Windows needs to send documents to the ML690.
• Print configuration: Gives access to the paper sizes, orientation options, and other settings supported by the selected driver.
• Network printing support: Can be used with an appropriately configured shared printer or network print connection; the driver alone does not add network connectivity.
• Windows compatibility: When choosing a package for Windows 11, 10, 8, or 7, check its release notes for your exact operating system and system architecture.

How to Install Okidata ML690 Driver

1. Check your Windows version. Open your system information and confirm your Windows edition and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11, make sure the package explicitly supports your system.
2. Choose a compatible package. Before starting an Okidata ML690 driver download for Windows, confirm the model name and review the compatibility information. Look for the latest version offered for your setup, rather than assuming every newer package will work.
3. Prepare the printer. Turn on the ML690 and check its connection. For network printing, confirm that the shared printer or print server is reachable.
4. Install the driver. Extract the downloaded files if necessary, then run the installer. If no installer is included, use Windows’ Add printer option and select the supplied driver files.
5. Test the setup. Print a test page and check paper handling and output. If printing fails, verify the selected printer port and connection before reinstalling.

Keep the driver updated when a compatible release addresses an issue you encounter or supports a Windows change. Choose a trusted free download source, review the update notes, and retain the working installer in case you need to restore your previous setup.

Common Issues and Fixes

• Install fails or stalls: Remove any existing Okidata/ML-series printer entry in Print Management, reboot, then run the ML690 installer as administrator. Use the correct 32/64-bit package and avoid the generic Windows dot-matrix driver.
• Device not detected: Confirm the ML690 is powered on and connected directly—USB to the PC, or parallel to the correct LPT port. Check Device Manager/BIOS for the port; avoid unpowered hubs or adapters.
• Version conflicts / wrong output: Uninstall older ML690 or Oki drivers, clear the print queue, and reinstall the current Okidata driver. Set the correct paper form length and tractor-feed settings so continuous forms align properly.
