How to Print an Excel File in Node.js

Automating document printing gives your business a clear competitive advantage. By printing Excel files directly from Node.js you reduce manual effort, speed up workflows, and ensure consistent output. In this article we install the JS Excel library1 in a Node.js project, work with Excel files, and demonstrate how to print an Excel file in Node.js.

We will cover:

JS Excel library installation

The enterprise‑grade library is available via npm or as a downloadable package. Follow the official installation guide5 to set up the environment. Choose the method that fits your workflow:

npm install java
npm install aspose.cells

Or download the latest API bundle from the official site6 and include it in your project.

After the library is installed, you can write code that loads an Excel workbook, selects a worksheet, and sends it to a printer. Follow these detailed steps:

  1. Create a Workbook instance – Load the source Excel file using the WorkBook class.
  2. Configure printing options – Instantiate an ImageOptions (or PrintOptions) object to define page size, orientation, and quality.
  3. Select the target worksheet – Retrieve the first sheet with the get method9.
  4. Prepare the renderer – Build a SheetRender object for the chosen worksheet; this object can render the sheet to images or send it directly to a printer.
  5. Print the sheet – Call the toPrinter method11 on the renderer to launch the print job on the default printer.
