Jdk1.4 printing and AttibuteSets.

Question

Hi!
I'm trying to create a HTML -> PS filter, and I'm stumbling on the goal line... I bring up the URL in a HTML component, then use the new 1.4 printing API to write out PS. Unfortunately, my attributes seem to be ignored. I need to set attributes programatically (instead of via a PrintRequest) since my program is headless.
Time for some code. Here's the actuall attibute handling and printing:
     PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
     // Gray scale only, this is for faxes after all
     aset.add(Chromaticity.MONOCHROME);
     // Try to set right paper and reasonable margins.
     // A4=210x297 mm. 1 cm margins
     aset.add(MediaSizeName.ISO_A4);
     aset.add(new MediaPrintableArea(10, 10, 190, 277, MediaPrintableArea.MM));
     Printable p=new ComponentPrintable(c);
     Doc doc = new SimpleDoc(p, flavor, null);
     pj.print(doc, aset);I'm skipping some of the preliminaries, but everything works except the attributes so I focused on that bit.
Here's my ComponentPrintable:
static class ComponentPrintable implements Printable {
    Component component;
     ComponentPrintable(Component c) {
          component=c;
     public int print(Graphics g,PageFormat pf,int pageIndex) {
          if (pageIndex == 0) {
               Graphics2D g2d= (Graphics2D)g;
               double x0=pf.getImageableX(), y0=pf.getImageableY();
               double pw=pf.getImageableWidth(), ph=pf.getImageableHeight();
               int cw=component.getWidth(), ch=component.getHeight();
               double sc=((double)pw)/cw;
               System.out.println("Page dimension: ("+x0+","+y0+")-("+(x0+pw)+","+(y0+ph)+")");
               System.out.println("Comp dimension: "+cw+"x"+ch);
               System.out.println("Translate "+x0+","+y0);
               System.out.println("Scale "+sc);
               g2d.translate(x0, y0);
               g2d.scale(sc, sc);
               component.paint(g2d);
               return Printable.PAGE_EXISTS;
          } else {
               return Printable.NO_SUCH_PAGE;
}Output from the ComponentPrintable when run:
Page dimension: (72.0,72.0)-(540.0,720.0)
Comp dimension: 681x1009
Translate 72.0,72.0
Scale 0.6872246696035242
Page dimension: (72.0,72.0)-(540.0,720.0)
Comp dimension: 681x1009
Translate 72.0,72.0
Scale 0.6872246696035242One inch margin. And when viewing the PS file it turns out it's in color as well.
Why oh why aren't my attributes respected? Any and all suggestions welcomed.

Answer 1

Well, I was trying to use the unified printing APIs in 1.4, ie. javax.print.DocPrintJob and so forth. If you do it that way there is no PageFormat, just the attributes. In 1.3 style printing there was no way to print to a PostScript file.
But, lo and behold, I checked out the docs for 1.3-style printing (java.awt.print) in 1.4 and they have added methods to select a StreamPrintService based on output flavor. Then I could use a plain old PrintJob and PageFormat to fix the margins.
I'll give you partial credit for leading my right. However, I also need to get grayscale to work. The client's PS printing program crashes on 'textcolor' commands. :-(
Finished code if anyone is interested:
String psMimeType = DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType();
PrinterJob pj = PrinterJob.getPrinterJob();
StreamPrintServiceFactory[] factories =
     PrinterJob.lookupStreamPrintServices(psMimeType);
if (factories.length == 0) {
     System.err.println("No suitable factories");
     return false;
try {
     FileOutputStream fos = new FileOutputStream(f);
     StreamPrintService sps = factories[0].getPrintService(fos);
     pj.setPrintService(sps);
     PageFormat pf=pj.defaultPage();
     Paper p=new Paper();
     p.setSize(210*72d/25, 297*72d/25);
     p.setImageableArea(10*72d/25,10*72d/25, 190*72d/25,277*72d/25);
     pf.setPaper(p);
     pj.setPrintable(new ComponentPrintable(c), pf);
     pj.print();
} catch (Exception x) {
     x.printStackTrace();
     return false;
return true;
