java - 如何在java中设置打印机边距

Question

尝试使用 Print API 进行打印时 - 边距似乎不受我们控制!...请帮我设置打印机边距，或者有什么方法可以在操作系统级别设置边距。

默认情况下，左、右、上、下四个都设置为1。

Answer 1

I'm using the Java Printing API, but have problems setting print margins.

...

Solution

I had to provide additional print attributes to override the default print margins, MediaPrintableArea.

Most printers cannot print on the entire surface of the media, due to printer hardware limitations.

MediaPrintableArea can be used to query the acceptable values for a supposed print job, and to request an area within the constraints of the printable area to be used in a print job.

HashPrintRequestAttributeSet attr = new HashPrintRequestAttributeSet();
attr.add(new MediaPrintableArea(0f, 0f, w/72f, h/72f, MediaPrintableArea.INCH));       
PrinterJob job = PrinterJob.getPrinterJob();    
job.setPrintService(ps);
job.setPrintable(this);
job.setJobName(jobName);
job.print(attr);
j.setVisible(false);
j.dispose();

The key was to provide the attributes along with the print() command.
