Print PDF
The first step is to load the PDF document you want to print. The print method opens the standard print dialog, allowing you to select the printer, page range, and other options before printing. Here's an example:
import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
// Set the license key for IronPDF
License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");
// Render HTML to a PDF document
PdfDocument pdf = PdfDocument.renderHtmlAsPdf("<h1>testing</h1>");
// Print the PDF with a print dialog for user interaction
pdf.print();import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
// Set the license key for IronPDF
License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");
// Render HTML to a PDF document
PdfDocument pdf = PdfDocument.renderHtmlAsPdf("<h1>testing</h1>");
// Print the PDF with a print dialog for user interaction
pdf.print();You will be prompted with a print dialog to select the printer and options, as shown below.
Print PDF without the Print Dialog
The printWithoutDialog method bypasses the print dialog and sends the document straight to the default printer. This is useful in automation scenarios where no user interaction is needed.
import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
// Set the license key for IronPDF
License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");
// Render HTML to a PDF document
PdfDocument pdf = PdfDocument.renderHtmlAsPdf("<h1>testing</h1>");
// Print the PDF directly without showing a print dialog
pdf.printWithoutDialog();import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
// Set the license key for IronPDF
License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");
// Render HTML to a PDF document
PdfDocument pdf = PdfDocument.renderHtmlAsPdf("<h1>testing</h1>");
// Print the PDF directly without showing a print dialog
pdf.printWithoutDialog();Frequently Asked Questions
