Screen: Indicates that CSS rules are intended for on-screen viewing. Styles are optimized for digital screens, which typically include considerations like colors and layouts that look good on computer monitors.
Print: Instructs the browser to apply styles tailored for printed documents. This means the CSS rules are optimized for printing, ensuring readability and proper formatting when the HTML content is printed on physical media, like paper.

import {PdfDocument} from "@ironsoftware/ironpdf";

(async () => {
    // Configure render options
    const renderOptions = {
        // Set color to grayscale
        grayScale: true,
    };
    
    const pdf = await PdfDocument.fromHtml("my-content.html", { renderOptions });

    // Export the PDF document
    await pdf.saveAs("my-content.pdf");
})();

Set to Grayscale

Converting a colored PDF document to grayscale can offer several advantages, such as removing the consideration of color and focusing solely on color intensity.

The feature to generate grayscale PDFs is only available when converting HTML to PDF. You can apply a rendering option that includes a grayScale property, which can be set to true or false. Setting this property to true will generate a grayscale PDF instead of a colored one.
