Printing problem: Looks correct but no text gets printed.
Hi,
I am making a small GUI which at some point should print some text. But this never happens. I have supplied some parts of the code below, please let me know if you can find any errors, I have been looking at this for some time now and cannot get anywhere. Maybe I am doing it all wrong (please let me know if that's the case!).
In my main program:
if (actionevent.getActionCommand().equals("Print")){
PrintRequestAttributeSet aset =new HashPrintRequestAttributeSet();
// aset.add(OrientationRequested.PORTRAIT);
// aset.add(new Copies(1));
// aset.add(new JobName("My Job", null));
PrinterJob pj = PrinterJob.getPrinterJob();
// pj.setPrintable(this);
Book book =new Book();
PageFormat portrait =new PageFormat();
portrait.setOrientation(PageFormat.PORTRAIT);
String text = textarea.getText();
int pages = textarea.getText().split("[\n]").length/58+1;
System.out.println("THERE ARE: " + pages +"PAGES IN DOCUMENT.");
for (int i=0; i<pages; i++){
book.append(new makeGraphics(text, i), portrait);
System.out.println("JUST APPENDED PAGE " + i +" TO THE BOOK.");
}
System.out.println("THE BOOK CONTAINS " + book.getNumberOfPages() +" PAGES!");
pj.setPageable(book);
PrintService[] services = PrinterJob.lookupPrintServices();
if (services.length > 0){
System.out.println("Selected printer: " + services[0].getName());
try{
pj.setPrintService(services[0]);
if (pj.printDialog(aset))
pj.print();
}
catch (PrinterException pe){
System.err.println(pe);
}
}
else
System.out.println("No printers available");
}// end if (actionevent: print)
}
So it calls the makeGraphics() class which looks like:
class makeGraphicsimplements Printable{
publicint currentPage=0;
Font font =new Font("Monospaced",Font.PLAIN,12);
String[] tokens;
public makeGraphics(String text,int page){
currentPage=page;
tokens = text.split("[\n]");
}
publicint print(Graphics g, PageFormat pf,int PageIndex){
System.out.println("METHOD JUST CALLED BY PJ.PRINT()..." + currentPage);
if (PageIndex >= 0){
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
g2d.setColor(Color.black);
g2d.setFont(font);
int lineIndex=0;
for (int i=58*currentPage; i<58*(currentPage+1); i++){
if (i<tokens.length){
g2d.drawString(tokens[i], 8, 10+12*lineIndex);
System.out.println("Now printing: " + tokens[i]);
}
lineIndex++;
}
return Printable.PAGE_EXISTS;
}
else{
System.out.println("THAT PAGE DOES NOT EXIST...");
return Printable.NO_SUCH_PAGE;
}
}
}
Please advise/suggest.>
