我们最近购买了一台兄弟 QL-700打印机，我们正在通过这台机器进行一些不干胶打印。

我们送入的纸张是62 毫米宽的贴纸卷，没有“长度”限制。

问题是，无论我怎么做（我已经尝试过Book, PrintRequestAttributeSet），我都无法使用 Java 告诉打印机对话框窗口为打印机使用正确的纸张尺寸。例如，我无法按照我们的需要制作出精确的 62mm × 40mm。它总是像这样“捕捉”到最近的纸：

这是有问题的代码：

PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
Paper p = pf.getPaper();
p.setSize(UnitConv.mm2pt(62), UnitConv.mm2pt(40));
p.setImageableArea(0, 0, UnitConv.mm2pt(62), UnitConv.mm2pt(40));
pf.setPaper(p);
pf.setOrientation(PageFormat.LANDSCAPE);

job.setPrintable(this, pf);

if (job.printDialog()) {
    try {
        job.print();
    } catch (Exception PrintException) {
        PrintException.printStackTrace();
    }
}



我可以确认打印机可以打印任意长度，如下图所示（使用 Brother 的 P-touch 编辑器）。请注意，虽然它是可调节的，但它36mm是由软件本身预设的：

所以问题：

如何强制length纸张的“”精确到40mm？

只是为了更新这个问题的状态。最后我用python和一个开源实用程序brother_ql解决了它，它直接将作业发送到usb端口，甚至没有使用兄弟提供的固件。它工作得很好，解决了我的问题。

没有比这里更好的回答方式了

那么也不要混淆高度和长度和宽度，java中的纸类需要宽度和高度而不是长度

 public void setSize(double width, double height) {
    mWidth = width;
    mHeight = height;

你可能还想考虑这个

   /**
 * Sets the imageable area of this <code>Paper</code>.  The
 * imageable area is the area on the page in which printing
 * occurs.
 * @param x the X coordinate to which to set the
 * upper-left corner of the imageable area of this <code>Paper</code>
 * @param y the Y coordinate to which to set the
 * upper-left corner of the imageable area of this <code>Paper</code>
 * @param width the value to which to set the width of the
 * imageable area of this <code>Paper</code>
 * @param height the value to which to set the height of the
 * imageable area of this <code>Paper</code>
 */
public void setImageableArea(double x, double y,
                             double width, double height) {
    mImageableArea = new Rectangle2D.Double(x, y, width,height);
}

这些只是纸质类中的一些方法，当涉及到实现时，您可能想看看更多参数..希望它有所帮助:)

您可能需要在提交打印作业请求时使用PrintRequestAttribute。如果自定义打印介质尺寸不起作用，您可能希望使用通过查询代码发现的介质尺寸并在请求属性集中选择最合适的一个。

@Test
public void testMyPrinteService() {
    // select default or specific one here
    PrintService printService = PrintServiceLookup.lookupDefaultPrintService();

    PrinterJob job = PrinterJob.getPrinterJob();

    PageFormat pf = job.defaultPage();
    Paper p = pf.getPaper();
    p.setSize(UnitConv.mm2pt(62), UnitConv.mm2pt(40));
    p.setImageableArea(0, 0, UnitConv.mm2pt(62), UnitConv.mm2pt(40));
    pf.setPaper(p);
    pf.setOrientation(PageFormat.LANDSCAPE);

    Printable myPrintable = null ;//some printable new MyPrintable(1); 
    PrintRequestAttributeSet printReqAttrs = new HashPrintRequestAttributeSet();
    PrintRequestAttribute jobPrinArea = new MediaPrintableArea(0, 0, 64, 40, MediaPrintableArea.MM);
    printReqAttrs.add(jobPrinArea);

    if (job.printDialog(printReqAttrs)) {
        try {
            job.setPrintable(myPrintable, pf);
            job.setPrintService(printService);
            //pass specific attributes to printer
            job.print(printReqAttrs);
        } catch (Exception PrintException) {
            PrintException.printStackTrace();
        }
    }
}

希望这可以帮助。

使用自定义 java.awt.print.Paper 不适用于 Brother QL 标签打印机。

我已经为QL-720NW找到了一个解决方案，它几乎是相同的型号，只是带有 WiFi 和以太网。请注意，它应该适用于所有 Brother 标签打印机。

首先，您需要使用驱动程序添加自定义连续磁带格式。在 Windows 中，它位于：

打印机首选项 > 高级选项卡 > 连续磁带格式 > 设置

打印机设置

自定义纸张尺寸列表

添加自定义纸张

之后，您应该按照您选择的名称（例如，“自定义纸张”）找到介质并通过 javax.print API 打印：

// Lookup printer by name 
PrintService[] foundPrinters = PrintServiceLookup.lookupPrintServices(null, new HashAttributeSet(new PrinterName("QL-720NW", null)));
PrintService printer = foundPrinters[0];

// Lookup custom paper by name
MediaSizeName paper = null;
for (Media m : (Media[])printer.getSupportedAttributeValues(Media.class, null, null))
{
    if (m instanceof MediaSizeName)
    {
        MediaSizeName media = ((MediaSizeName)m);
        if ("Custom paper".equals(media.toString())) paper = media;
    }
}

// Create a new printable object
Printable p = ...; // Create a printable object
Doc doc = new SimpleDoc(p, DocFlavor.SERVICE_FORMATTED.PRINTABLE, null);

// Set custom paper as request attribute
PrintRequestAttributeSet attrs = new HashPrintRequestAttributeSet();
attrs.add(paper);

// Create a new print job and print it
DocPrintJob job = printer.createPrintJob();
try
{
    job.print(doc, attrs);
}
catch (PrintException ex)
{
    ex.printStackTrace();
}

我找到了一个适合我的解决方案。调用 printDialog() 后，您不能在 PrintJob 上设置打印 ()，但使用包装在 Book 对象中的 Printable 的 setPageable() 可以工作。第一个验证传递的 PageFormat 并选择另一个。

我已经看到很多次Paper setSize参数被传递保持像素大小。你能尝试这样改变mm2pt吗mm2px？

PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
Paper p = pf.getPaper();
int resolution = 72; // dpi
p.setSize(UnitConv.mm2px(62, resolution), UnitConv.mm2px(40, resolution));
p.setImageableArea(0, 0, UnitConv.mm2px(62, resolution), UnitConv.mm2px(40, resolution));
pf.setPaper(p);
pf.setOrientation(PageFormat.LANDSCAPE);

job.setPrintable(this, pf);

if (job.printDialog()) {
    try {
        job.print();
    } catch (Exception PrintException) {
        PrintException.printStackTrace();
    }
}
