Sometimes, developers need to configure page setup and print settings to control the printing process. Page setup and print settings offer various options and are fully supported in Aspose.Cells.
This article shows how to create a console application in JavaScript via C++, and apply page setup and printing options to a worksheet with a few simple lines of code using the Aspose.Cells API.
Working with Page and Print Settings
For this example, we created a workbook in Microsoft Excel and used Aspose.Cells to set page setup and print options.
Using Aspose.Cells to set Page Setup Options
First create a simple worksheet in Microsoft Excel. Then apply page setup options to it. Executing the code changes the Page Setup options as in the screenshot below.
| Output file. |
|---|
 |
- Create a worksheet with some data in Microsoft Excel:
- Open a new workbook in Microsoft Excel.
- Add some data.
- Set page setup options:
Apply page setup options to the file. Below is a screenshot of the default options, before the new options are applied.
| Default page setup options. |

- Download and install Aspose.Cells:
- Download Aspose.Cells for JavaScript via C++.
- Install it on your development computer.
All Aspose components, when installed, work in evaluation mode. The evaluation mode has no time limit and it only injects watermarks into produced documents.
- Create a project:
- Start your JavaScript environment.
- Create a new console application.
This example will show a JavaScript console application, but you can use C++ bindings too.
- Add references:
- This example uses Aspose.Cells so add a reference to that component to the project. For example:
…\Program Files\Aspose\Aspose.Cells\Bin\JavaScript-Cpp\Aspose.Cells.node
- This example uses Aspose.Cells so add a reference to that component to the project. For example:
- Write the application that invokes the API:
<!DOCTYPE html>

<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Page Setup Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>
<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, PageOrientationType, PaperSizeType } = AsposeCells;
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
if (!fileInput.files.length) {
document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiate workbook from uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Accessing the first worksheet in the Excel file
const worksheet = workbook.worksheets.get(0);
// Access page setup as a property
const pageSetup = worksheet.pageSetup;
// Setting the orientation to Portrait
pageSetup.orientation = PageOrientationType.Portrait;
// Setting the number of pages to which the length of the worksheet will be spanned
pageSetup.fitToPagesTall = 1;
// Setting the number of pages to which the width of the worksheet will be spanned
pageSetup.fitToPagesWide = 1;
// Setting the paper size to A4
pageSetup.paperSize = PaperSizeType.PaperA4;
// Setting the print quality of the worksheet to 1200 dpi
pageSetup.printQuality = 1200;
// Setting the first page number of the worksheet pages
pageSetup.firstPageNumber = 2;
// Save the workbook and provide download link
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'PageSetup_out.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Page setup modified successfully! Click the download link to get the modified file.</p>';
});
</script>

Setting Print options
Page setup settings also provide several print options (also called sheet options) that allow users to control how worksheet pages are printed. They allow users to:
- Select a specific print area of a worksheet.
- Print titles.
- Print gridlines.
- Print row/column headings.
- Achieve draft quality.
- Print comments.
- Print cell errors.
- Define page ordering.
The example that follows applies print options to the file created in the example above (PageSetup.xls). The screenshot below shows the default print options before new options are applied.
| Input document |

| Executing the code changes the print options. |
