The Epson LQ 350 ESC P2 Printer driver allows Windows to communicate with your Epson dot matrix printer and send print jobs using the appropriate commands. Installing a compatible driver helps you configure paper handling and print settings for everyday documents, continuous stationery, and multipart forms.

Key Features

• Printer communication: Provides the software interface Windows needs to send documents to the Epson LQ 350 using ESC/P2 printer commands.
• Paper and layout settings: Gives access to supported paper sizes, orientation, and other layout options so you can match the print setup to your stationery.
• Print output controls: Lets you adjust available quality and printing preferences to suit text-heavy reports, invoices, and forms.
• Windows integration: Makes the printer available through standard Windows printing dialogs and applications once installation and connection are complete.

How to Install

1. Check your Windows version. Identify whether your computer runs Windows 11, 10, 8, or 7, and check its system architecture. Select an Epson LQ 350 ESC P2 Printer driver package that explicitly supports your configuration; compatibility can vary by package.

1. Download the appropriate driver. Save the compatible Epson driver to a folder you can easily find. If it comes in a compressed archive, extract the contents before starting installation.

1. Prepare the printer. Load suitable paper and make sure the printer is ready for use. Follow the installer’s instructions about when to connect and power on the printer, especially when using USB.

1. Install the driver. Run the setup program and follow the prompts. If the package has no installer, use the Windows Add Printer wizard and select the extracted driver files when asked. Choose the port that matches your printer connection.

1. Check the setup and print a test page. Open the printer’s properties or printing preferences in Windows, confirm the paper size and layout, and send a test page. For continuous paper or preprinted forms, check alignment before printing a full batch.

If the printer does not respond, verify the cable connection, selected port, and print queue status before reinstalling. Incorrect paper dimensions or application margins can also cause misaligned output, even when the driver is installed correctly.

Common Issues and Fixes

• Install fails or stalls: Run the Epson LQ-350 ESC/P2 installer as administrator, disconnect the printer until prompted, and remove any previous LQ-series driver before retrying. Use the package matching your Windows architecture.
• Printer not detected: Check that the USB or parallel cable is firmly connected and try a rear USB 2.0 port directly on the PC. For parallel models, verify the port mode in BIOS and avoid unsupported USB-to-parallel adapters. Power-cycle the printer and print a self-test.
• Version conflicts or wrong output: Delete old Epson LQ-300/350 printer queues in Printers & scanners, restart Windows, then reinstall the ESC/P2 driver. In Printer Properties, confirm the correct LQ-350 model and paper source; do not substitute a laser/inkjet driver.
