It sems that certain characters in the "Dialog" font family broke the
painting (first line is Arial, second Times New, third Dialog):

[image: Immagine in linea 1]

This is the code to produce the output:

public class ArtifactsWhenUsingDialogFont {

    public static void main(String... args) throws Exception {
      PrinterJob job = PrinterJob.getPrinterJob();
      job.setPrintService(PrintServiceLookup.lookupDefaultPrintService());
      job.setPrintable(new Printable(){

          @Override
          public int print(Graphics graphics, PageFormat pageFormat,
int pageIndex) throws PrinterException {
            graphics.translate( (int) pageFormat.getImageableX(),
(int) pageFormat.getImageableY() );
            final String target =
"OOOOOOOOOO\u2014MMMMMMMMM\u2014IIIIIIIIII\u2014";
            printLine(graphics, target, "Arial");
            printLine(graphics, target, "Times New Roman");
            printLine(graphics, target, "Dialog");
            return pageIndex == 0 ? PAGE_EXISTS : NO_SUCH_PAGE;
          }

          private int lineCounter = 0;

          private void printLine(Graphics graphics, String text,
String fontName) {
            graphics.setFont(new Font(fontName, Font.PLAIN, 20));
            graphics.drawString(text, 20, 20 * ++lineCounter);
          }
      });
      job.print();
    }}

The problem is that the "Dialog" font family appears to be the default one,
at least on the Windows platform. Is this a known bug?
