Print forms directly to the printer with JasperReports

Overview

With JasperReports, output directly to the printer without outputting the file to PDF etc. A memo of the result of the investigation because there were unusual requirements as mentioned above in the business. There was some sample code on the net, but since the version was old and used a deprecated API, I created a sample to support 6.8.

Environment etc.

• JasperReports（6.8.0）
• Jaspersoft Studio (6.8.0) * Used for template creation
• Java（1.8）

Form template

Assuming the following fictitious quotation

Form parameter list

Form field list

Sample code

• Since this is just a sample, the parameters and field settings are set directly in the code.

Main.java

public class DirectPrintSample {

	/**JasperReport template file*/
	public static final String REPORT_TEMPLATE = "template/quotation.jrxml";

	/**Output destination printer name*/
	public static final String PRINTER_NAME = "(Output printer name)";

	public static void main(String[] args) {

		//Initialize the form definition
		JasperReport report = null;
		try {
			report = createReport();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (JRException e) {
			e.printStackTrace();
		}

		//Create a document (set output data in form definition)
		JasperPrint print = null;
		try {
			print = createPrint(report);
		} catch (JRException e) {
			e.printStackTrace();
		} catch (ParseException e) {
			e.printStackTrace();
		}

		//Directly print the form by specifying the printer
		try {
			exportPrint(print, PRINTER_NAME);
		} catch (JRException e) {
			e.printStackTrace();
		}
	}

	/**

Item.java

public class Item {

	private String item;
	private int quantity;
	private int unit;
	private int price;

	Item(String item, int quantity, int unit, int price) {
		this.item = item;
		this.quantity = quantity;
		this.unit = unit;
		this.price = price;

	public String getItem() {

Output result

The following is a PDF output with the output destination set to Microsoft Print to PDF.

Issues / concerns

• In order to output directly to the printer, the AP server and the printer must exist on the same LAN, so when mounting on a cloud server etc., it is necessary to make the printer compatible with IPsec etc.
