Re: FOP AWTRenderer Printing issue

I have now upgraded to fop 0.93.  However I still have the same issue with some
of our customers printing half or 1/3 of the print on one page.  It has to be a
memory issue, but I'm at a lost to know how to fix it. 

Any suggestions?

No, unfortuately it is only a problem on the terminal server, and yes I agree
it's very hard to find issues like this.

I am calling the print dialog so the printer can be selected.  This is the full
method.

    public void print() {
        PrinterJob pj = PrinterJob.getPrinterJob();

        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        
        SimpleDoc doc = new SimpleDoc(renderer,
               DocFlavor.SERVICE_FORMATTED.PAGEABLE, null);

        if (pj.printDialog(aset)) {
            try {
            	PrintService ps = pj.getPrintService();
            	DocPrintJob dpj = ps.createPrintJob();
                dpj.print(doc, aset);
            } catch (PrintException pe) {
                pe.printStackTrace();                
            }
        }
    }

I can try generating the pcl or ps output, but I was concerned that some
printers might not support that.

But not on a developer machine with a similar setup?

So you're probably just printing to the default printer. So with printer
driver, I'm wondering if you're using a PCL or PostScript printer driver
to print to the printer. Some printers support several printer formats,
especially the bigger network-connected ones. What you could try is to
check if it gets better if you switch to a different printer driver (if
you're on PCL, switch to PostScript).

It's generally a little difficult to reproduce problems like these in
different environments. I can't promise that I can find out anything,
but I'll see if I can.

The problem shows up on our terminal server - running windows server 2003 R2
enterprise.

The jvm is Sun java 1.5.0.08.

The printers vary - we have several clients, there are around 75 different
printers, most are HP laserjets.

I'm not sure what you mean by the printer driver, I've been using the print
method from the fop awt viewer program.  It uses:
 
      SimpleDoc doc = new SimpleDoc(renderer,
                        DocFlavor.SERVICE_FORMATTED.PAGEABLE, null);

The renderer is the AWTRenderer used to display the report prior to viewing.

Hmm, can you please give me a little more information?
- Operating System
- Java version and brand
- Printer Model
- Printer language generated by the printer driver you use (PCL,
PostScript, GDI etc...)

Maybe I can then try to reproduce your problem.
