在热敏打印机上使用java print（）打印长收据的问题

Question

我无法打印超过（几乎）A4高度纸张尺寸的热敏收据（8厘米）。程序仅打印（直到几乎默认）A4尺寸。收货的其余部分丢失了。

小收据一切正常。只有长收据才会出现问题，因为票据缩短了。我动态设置纸张高度计数要打印的行。我也尝试手动将纸张尺寸和imageablearea设置为大尺寸，但是徒劳无功。

我尝试使用Print.Book类对象，但没有任何改进。

（注意：用另一种语言编写的另一个程序，在同一台打印机上打印相同的帐单）

如果我遗漏了某些内容或如何删除此限制，请告诉我。

public void printReciept()
    {        
        PrinterJob pj = PrinterJob.getPrinterJob();        
        pj.setPrintable(new BillPrintable(),getPageFormat(pj));
        try {
             pj.print();

        }
         catch (PrinterException ex) {
                 ex.printStackTrace();
        }
    }




public PageFormat getPageFormat(PrinterJob pj)
{

    PageFormat pf = pj.defaultPage();
    Paper paper = pf.getPaper();    

    double middleHeight =this.productList.size()*1.0;  //dynamic----->change with the row count of jtable
    double headerHeight = 5.0;                  //fixed----->but can be mod
    double footerHeight = 5.0;                  //fixed----->but can be mod

    double width = convert_CM_To_PPI(8);      //printer know only point per inch.default value is 72ppi
    double height = convert_CM_To_PPI(headerHeight+middleHeight+footerHeight); 
    paper.setSize(width, height);
    paper.setImageableArea(                    
        0,
        10,
        width,            
        height - convert_CM_To_PPI(1)
    );   //define boarder size    after that print area width is about 180 points

    pf.setOrientation(PageFormat.PORTRAIT);           //select orientation portrait or landscape but for this time portrait
    pf.setPaper(paper);    

    return pf;
}




public class BillPrintable implements Printable {


 @Override
  public int print(Graphics graphics, PageFormat pageFormat,int pageIndex) 
  throws PrinterException 
  {    
        String title[] = {"Product Name","Disc","Rate","Qty","AMT"};      
        int result = NO_SUCH_PAGE;    
        if (pageIndex == 0) {                    

            Graphics2D g2d = (Graphics2D) graphics;                

            g2d.translate((int) pageFormat.getImageableX(),(int) pageFormat.getImageableY());
