Question

我看了this和this，但我无法打印到Brother QL-700标签打印机。我总是得到以下例外：

java.lang.IllegalArgumentException: Bad margins

我要打印的标签是38mm X 30mm。这是我的代码：

Printer printer = Printer.getDefaultPrinter();
Paper label = PrintHelper.createPaper("38x30", 38, 30, Units.MM);
PageLayout pageLayout = printer.createPageLayout(label, PageOrientation.LANDSCAPE, Printer.MarginType.EQUAL);

PrinterJob job = PrinterJob.createPrinterJob();
double scaleX = pageLayout.getPrintableWidth() / node.getBoundsInParent().getWidth();
double scaleY = pageLayout.getPrintableHeight() / node.getBoundsInParent().getHeight();
node.getTransforms().add(new Scale(scaleX, scaleY));
if (job != null  && job.showPrintDialog(node.getScene().getWindow()) ) {
boolean success = job.printPage(node);
    if (success) {
        job.endJob();
    }
}

更新1：

我在这里得到例外：

job.showPrintDialog(node.getScene().getWindow())

更新2：

printer.getPrinterAttributes().getSupportedPapers()

告诉我：

我发现public PageLayout createPageLayout(Paper paper, PageOrientation orient, MarginType mType)类中的函数Printer将边距乘以72（我认为是dpi）。由于这一点，我认为我的利润率很低。但我不明白为什么。我也将所有边距设置为零，结果相同。 PageLayout pageLayout = printer.createPageLayout(tmp, PageOrientation.PORTRAIT,0f,0f,0f,0f);

我尝试this并且它有效。但仅限于给定的大小double width = fromCMToPPI(3.5); double height = fromCMToPPI(8.8);。如果我将高度设置为3.3则无法正常工作

我可以用这段代码打印：

DocFlavor flavor = DocFlavor.INPUT_STREAM.JPEG;
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
Media[] res = (Media[]) printService.getSupportedAttributeValues(Media.class, null, null);

aset.add(OrientationRequested.PORTRAIT);
aset.add(res[14]);

DocPrintJob pj = printService.createPrintJob();

FileInputStream fis = new FileInputStream("test.jpg");
Doc doc = new SimpleDoc(fis, flavor, null);
pj.print(doc, aset);

但现在问题是身高。我有很多空间。如何设置纸张的高度？顺便说一下它的无穷无尽的纸张和res [14]意味着38毫米无穷无尽。

如何在JavaFX中打印到特定的纸张布局
