Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    OutputStream fos = new BufferedOutputStream(new FileOutputStream("filename.ps"));
    DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF;
    StreamPrintServiceFactory[] factories = StreamPrintServiceFactory.lookupStreamPrintServiceFactories(flavor,
            DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType());

    StreamPrintService service = factories[0].getPrintService(fos);
    Class[] cats = service.getSupportedAttributeCategories();
    for (int j = 0; j < cats.length; j++) {
        Attribute attr = (Attribute) service.getDefaultAttributeValue(cats[j]);

        if (attr != null) {
            String attrName = attr.getName();
            String attrValue = attr.toString();

            Object o = service.getSupportedAttributeValues(attr.getCategory(), null, null);
            if (o.getClass().isArray()) {
                for (int k = 0; k < Array.getLength(o); k++) {
                    Object o2 = Array.get(o, k);
                    System.out.println(o2);
