无法指定正确的打印尺寸

Question

我们最近收购了兄弟QL-700打印机,我们正在通过这台机器进行贴纸打印.

我们喂食的纸是62毫米宽的贴纸卷,没有"长度"限制.

问题是,不管我怎么做(我试过Book,PrintRequestAttributeSet),我无法使用Java来告诉打印机对话窗口使用正确的纸张尺寸打印机.我无法做到,例如,我们需要的确切的62毫米×40毫米.它总是"按下"到最近的纸张:

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随意打印,如下面的屏幕截图所示(使用Brother的P-touch编辑器).请注意,虽然它是可调整的,但是36mm由软件本身预设:

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.最后我通过使用python和一个开源实用程序brother_ql来解决它,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.它完美无缺,解决了我的问题.

没有比这里更好的回答方式了

然后也不要混淆高度和长度和宽度，java中的paper类采用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 Paper 类中的一些方法，您在实现时可能需要查看更多参数，因此希望它有所帮助:)
