OKI MICROLINE 591 Driver

The OKI MICROLINE 591 driver allows Windows to communicate with your dot-matrix printer and send print jobs using the appropriate device settings. It is useful when setting up the printer on another computer, restoring printing after a system change, or replacing a missing driver. This listing identifies Microsoft as the driver vendor and lists support for Windows 10, 8.1, 7, Vista, and XP.

Key Features

• Printer recognition: Helps Windows identify the OKI MICROLINE 591 and make it available to applications through the standard printing interface.
• Print configuration: Provides access to supported printer preferences, such as paper size and orientation, with available options depending on the driver and connection.
• Legacy Windows support: Offers a driver option for the listed Windows versions, helping keep an existing printer setup usable.
• Driver replacement: Can help restore communication when the installed driver is missing or damaged, though connection and hardware problems may need separate troubleshooting.

How to Install OKI MICROLINE 591 Driver

1. Check your Windows version. Confirm your operating system and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 10 is listed as supported here; Windows 11 compatibility is not confirmed.
2. Choose the matching package. Before starting your OKI MICROLINE 591 driver download for Windows, review the compatibility information. If multiple packages are available, select the latest version explicitly intended for your system, and verify the source of any free download.
3. Prepare the printer and files. Turn on the printer, check its connection, and extract the downloaded files if they are compressed. Follow any included instructions about when to connect the device.
4. Install the driver. Run the supplied installer if one is included. Otherwise, use Windows’ Add Printer wizard, select the appropriate connection or port, and use “Have Disk” when prompted to locate the extracted driver files.
5. Verify printing. Select the OKI MICROLINE 591 model, complete setup, and print a test page. If output is incorrect, check the selected port, paper settings, and printer configuration.

Keep the driver updated by checking Windows Update or a trusted driver source when printing issues arise or your operating system changes. Before you update, confirm that the replacement supports your exact setup; a newer package is not automatically a better match for an older printer.
