Created attachment 23537 [details]
the PrintRenderer

The attached PrintRenderer uses the Java Print Service API, introduced in Java 1.4.
It allows to programmatically set print options, like the destination printer and media tray. I use it like this:

// Construct a FopFactory
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent userAgent = fopFactory.newFOUserAgent();

// Setup FOP print renderer
PrintRenderer renderer = new PrintRenderer();
renderer.setUserAgent(userAgent);
userAgent.setRendererOverride(renderer);

// Construct fop with desired output format
Fop fop = fopFactory.newFop(MimeConstants.MIME_FOP_PRINT, userAgent);
ContentHandler handler = fop.getDefaultHandler();

// lookup a printer
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob job = service.createPrintJob();
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
// set print request attributes here, like the media tray

// print
job.print(renderer, attributes);

If this PrintRenderer replaced the current one (hint, hint), I could skip the "Setup FOP print renderer" section.
