How to set printer margin in java

问题

when trying to print using the Print API - the margins seem to be something not in our control!.. Please help me out to set printer margins or is there any way to set margins at Operating system level.

By default all the four left, right, top and bottom are set to 1.

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.
