JourneyPrinter
Version compatibility
This feature was introduced in version 19.12.2 of the JourneyApps Container for iOS and Android, and version 20.4.1 for Desktop. Version 4.72.0 of the JourneyApps Runtime is also required.
JourneyApps can print a PDF directly using the native printing capabilities provided by the operating system.
You can also check that printing is supported:
var capabilities = JourneyPrinter.getCapabilities();
Returns
{
print: true|false,
generatePdf: true|false
}
Note: For Runtime versions below 4.72.0, the
JourneyPrinter object will not be available.To print a PDF, you need to provide the
JourneyPrinter.printPDF function a PDF in the format of an ArrayBuffer or a base 64 string. In the case of an attachment object, helper functions are available: // Print a PDF from an ArrayBuffer:
JourneyPrinter.printPdf(view.pdf.toArrayBuffer());
// Print a PDF from base 64 string:
JourneyPrinter.printPdf(view.pdf.toBase64());
The origin of the PDF data can also be another source, e.g. using an
<html/> component to generate a PDF and send it in base 64 format to the app to be printed.This feature was introduced in version 20.10.1 of the JourneyApps Container for Desktop. It is not available on mobile or web containers. Version 4.77.0 of the JourneyApps Runtime is also required.
JourneyPrinter.generatePdf(htmlString, options);
where
htmlString is a string of HTML with @page or @media print CSS rules to control how the PDF is displayed. In addition, the <head> tag of the HTML must also contain this <meta> tag: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
and optional
options:value | Details | Default |
|---|---|---|
landscape | Boolean to generate the PDF in landscape orientation | false |
marginType | Number to specify the type of margin. 0 - default margin, 1 - no margin, 2 minimum margin | 0 |
printBackground | Boolean to choose to print the background | true |
pageSize | Size of the page. 'A3', 'A4', 'A5', 'Legal', 'Letter', 'Tabloid' | 'A4' |
Returns: The generated PDF as an ArrayBuffer.
var capabilities = JourneyPrinter.getCapabilities();
if (capabilities.generatePdf == true) {
// generate a PDF from an HTML string
var generatedPdf = JourneyPrinter.generatePdf(htmlString, options);
// create an Attachment object from the generated PDF ArrayBuffer:
view.generatedPdf = Attachment.create({data: generatedPdf, mediaType: 'application/pdf'});
}
