The Bixolon SLP D420 driver allows Windows to communicate with your label printer and send print jobs using the correct settings. Install the appropriate Bixolon driver for Windows 11, 10, 8, or 7 to configure label layouts and use the printer from compatible applications.

Key Features

• Windows printing integration: Makes the Bixolon SLP D420 available as a printer in compatible label-design software and other Windows applications.
• Label format configuration: Provides settings for label dimensions and orientation, helping match your document layout to the loaded media.
• Print output controls: Offers access to supported printing preferences, such as speed and darkness, so you can adjust output for your labels.
• Connection setup: Associates the printer with the correct Windows port so print jobs reach the intended device.

How to Install

1. Choose the appropriate driver. Check your Windows version and system architecture, then select a Bixolon SLP D420 driver package that explicitly supports them. Confirm compatibility before downloading, particularly for Windows 11.
2. Prepare the printer. Load the labels, connect the power supply, and turn on the device. If using USB, follow the installer’s instructions about when to connect the cable.
3. Run the installer. Extract the downloaded package if necessary, then open the setup program. Allow administrator access when prompted and follow the installation instructions.
4. Select the model and connection. Choose the SLP D420 if the installer asks for a printer model, and select the port that matches your connection. Complete setup and restart Windows if requested.
5. Check settings and test. Open the printer’s preferences in Windows, set the correct label size and orientation, and print a test label. If alignment is off, check that the media settings in both the driver and your label application agree.

For reliable results, use a driver intended for this model rather than a generic printer driver. If the printer does not respond after installation, check its power, cable connection, selected port, and print queue before reinstalling.

Common Issues and Fixes

• Install fails or rolls back: Download the correct Bixolon SLP-D420 driver for your Windows version/bitness. Run the installer as administrator, power the printer off until prompted, and remove failed Bixolon entries in Print Management before retrying.
• Printer not detected: Connect directly to a USB 2.0 port with a known data cable, power on the SLP-D420, and check Device Manager for unknown devices. Install/update the driver manually if needed.
• Driver/version conflicts: Delete duplicate SLP-D420 queues and old Bixolon drivers in Print Management > Drivers, restart Print Spooler, then reinstall the latest driver. Confirm the correct USB/Serial port and label size.
