I need to print one jasperreport,
Today I use this code:
try {
Resource resource = resourceLoader.getResource(resourceLoader.CLASSPATH_URL_PREFIX + "/static/relatorios/ReciboMovimentacaoMultiPedidos.jrxml");
JasperDesign jasperDesign = JRXmlLoader.load(resource.getInputStream());
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Map<String,Object> parametros = new HashMap<>();
parametros.put("idMovimentacao",idMovimentacao);
StreamResource.StreamSource source = new StreamResource.StreamSource() {
public InputStream getStream() {
byte[] b = null;
try{
b = JasperRunManager.runReportToPdf(jasperReport,parametros, jdbcTemplate.getDataSource().getConnection());
} catch (Exception e) {
e.printStackTrace();
}
return new ByteArrayInputStream(b);
}
};
StreamResource resourcesReport = new StreamResource(source, "ServicosPorPeriodo" + System.currentTimeMillis() + ".pdf");
BrowserWindowOpener opener = new BrowserWindowOpener(resourcesReport);
Button downloadButton = new Button(FontAwesome.DOWNLOAD);
panelDownload.addComponent(downloadButton);
panelDownload.setComponentAlignment(downloadButton, Alignment.MIDDLE_RIGHT);
opener.extend(downloadButton);
}catch (Exception e){
e.printStackTrace();
}
But I dont want to show another button to my user click in this button to open a new window, and then click the print button

The first link only show how to print a PDF opening a window(just like my sample) I need to send direclty to and not make my user click in a button.
and 2 link dont work.
tks
The second link works for me.
You need to call the following code on the ui / view where you display your result.
JavaScript.getCurrent().execute("print();");
Nice. but how I open the window without obrigate my user to click in button
tks
Hello,
Using javascript print() function works well for a web-html page. If your pdf is simple enough, it could be easier to achieve it this way : you render html page adding a post-loading print() then close() function (purely js inside HTML page).
If you really need pdf file, you are hard-linked to the viewer. Acrobat plugin will not react the same as internal browser viewer will do... May be you can control all the steps using pdfjs addon ( https://vaadin.com/directory#!addon/pdfviewer )

In case someone needs it, I implemented a demo that shows how to automatically open the browser's "print dialog" for a PDF file: https://github.com/alejandro-du/print-pdf-demo
