#Printing

Webswing implements seamless printing support, which works out of the box without any change needed in your application. Webswing generates a PDF file from the printed document and opens it in a new browser tab using default browser PDF viewer.

Printing is demonstrated in Webswing Demo application with sample source code included.

Multiple printing options are supported:

• print using javax.print.DocPrintJob.print()
• print using java.awt.print.Printable and java.awt.print.PrinterJob.print()
• print using java.awt.Desktop.getDesktop().print()
• print multiple pages using java.awt.print.Pageable and java.awt.print.PrinterJob.print()
• print GUI using java.awt.Toolkit.getDefaultToolkit().getPrintJob()
• print using JasperReports
• embedding fonts in printed PDF file (see Embed fonts in PDF)

#Server printing

If you want to use printers connected to the remote server when printing, you can enable this in Webswing app configuration.

#Direct printing

Webswing prints by generating PDF files on server and serving it to the client's browser. However, if you need to print directly from Webswing application to the client's printer, there are some options how to do this. You can create a custom print page that shows a printing dialog, that user must submit. To remove the user submission step you can start the browser in kiosk mode. Refer to this documentation for more information.

#Custom print service

Since Webswing 22.2 the print service is customizable. Please follow these steps:

1. Implement a print service class that implements org.webswing.ext.services.PdfService interface included in webswing-app-toolkit project.
2. Put JAR with the class in /extensions folder in webswing installation folder.
3. Run application with system property -Dorg.webswing.ext.services.PdfService=com.company.CustomPdfService
