The Dell 1720dn driver allows Windows to communicate with your laser printer, translating documents into print jobs and providing access to printer settings. Installing a suitable driver can help resolve recognition problems, restore missing print options, and support everyday printing over USB or a network.

Key Features

• Print quality and paper controls: Adjust available settings such as resolution, paper size, media type, and page orientation to suit your documents.
• Automatic two-sided printing: Access the Dell 1720dn’s duplex capability to print on both sides of the paper, reducing paper use for reports and longer documents.
• USB and network connectivity: Set up the printer through a direct USB connection or use its Ethernet connection to make it available on your local network.
• Tray and layout options: Select available paper sources and configure document layout settings supported by the installed driver.

How to Install

1. Check your Windows version. Confirm whether your computer runs Windows 11, 10, 8, or 7, and check its system type in Windows Settings or System Properties. Choose a driver package that explicitly supports your operating system and architecture; older packages may not support newer Windows releases.

1. Prepare the printer connection. Turn on the Dell 1720dn and load paper. For Ethernet setup, connect the printer to your router or switch and locate its IP address using the printer’s network settings page. For USB installation, follow the installer’s instructions about when to connect the cable.

1. Download and open the driver package. Save the compatible Dell printer driver to your computer. Extract the files if necessary, then launch the setup program and approve the Windows permission prompt if requested.

1. Complete printer setup. Select USB or network installation when prompted. If the package has no installer, use Windows’ Add printer option and browse to the extracted driver files. For a network printer that is not discovered automatically, try adding it by IP address.

1. Verify the installation. Open the printer’s properties and print a test page. Check paper size, tray selection, and duplex settings before printing your documents.

If no package lists support for your Windows version, check for a compatible driver through Windows Update rather than assuming an older installer will work. Available settings can differ between Dell-provided drivers and Windows-supplied alternatives.

Common Issues and Fixes

• Install fails or stalls: Stop the Print Spooler service, remove any old “Dell 1720dn” printer/driver entries in Print Management, reboot, then run the Dell package as administrator.
• Printer not detected: For USB, try a rear port and a known-good cable; for network use, confirm the printer has an IP address and add it with a Standard TCP/IP port instead of relying on auto-discovery.
• Driver version conflicts: Uninstall Windows inbox/universal Dell printer drivers first, match the package to your Windows version and architecture, then reinstall the Dell 1720dn driver and set it as default.
