Hi everyone,
I have a question about the java multi-platform print dialog.
My question is on collating the output of my print out using the java
multi-platform print dialog. The thing is no matter even if i select the
collate check box or not the output of the print out is always printed
uncollated.
When i use the platform specific print dialog(windows in my case) the
output can be printed collated or uncollated.
This is what i am doing to call the multi-platform dialog to print
collated print-outs
The below is sun's simple printing program but when i test this
programming(when i switch the aset variable between collating and
uncollating) the problem also arises.
This is the compilable program
import java.awt.*;
import java.awt.print.*;
import javax.print.attribute.standard.*;
public class PrintBook {
public static void main(String[] args) {
javax.print.attribute.PrintRequestAttributeSet aset;
aset = new javax.print.attribute.HashPrintRequestAttributeSet();
aset.add(new Copies(2));
//aset.add(SheetCollate.UNCOLLATED);
aset.add(SheetCollate.COLLATED);
// Get a PrinterJob
PrinterJob job = PrinterJob.getPrinterJob();
// Create a landscape page format
PageFormat pfl = job.defaultPage();
pfl.setOrientation(PageFormat.LANDSCAPE);
// Set up a book
Book bk = new Book();
bk.append(new PaintCover(), pfl);
bk.append(new PaintContent(), job.defaultPage());
// Pass the book to the PrinterJob
job.setPageable(bk);
// Put up the dialog box
if (job.printDialog(aset)) {
// Print the job if the user didn't cancel printing
try { job.print(aset); }
catch (Exception e) {e.printStackTrace();}
}
System.exit(0);
}
}
class PaintCover implements Printable {
Font fnt = new Font("Helvetica-Bold", Font.PLAIN, 72);
public int print(Graphics g, PageFormat pf, int pageIndex)
throws PrinterException {
g.setFont(fnt);
g.setColor(Color.black);
int yc = (int) (pf.getImageableY() +
pf.getImageableHeight()/2);
g.drawString("Widgets, Inc.", 72, yc+36);
return Printable.PAGE_EXISTS;
}
}
class PaintContent implements Printable {
public int print(Graphics g, PageFormat pf, int pageIndex)
throws PrinterException {
Graphics2D g2 = (Graphics2D) g;
int useRed = 0;
int xo = (int) pf.getImageableX();
int yo = (int) pf.getImageableY();
// Fill page with circles or squares, alternating red & green
for (int x = 0; x+28 < pf.getImageableWidth(); x += 36)
for (int y = 0; y+28 < pf.getImageableHeight(); y += 36){
if (useRed == 0) g.setColor(Color.red);
else g.setColor(Color.green);
useRed = 1 - useRed;
if (pageIndex % 2 == 0) g.drawRect(xo+x+4, yo+y+4, 28, 28);
else g.drawOval(xo+x+4, yo+y+4, 28, 28);
}
return Printable.PAGE_EXISTS;
}
}
It seems strange to me that if i use the sytem specific print dialog i can
print both collated and uncollated printouts but if i use the java
multi-platform print dialog the print out is always printed uncollated
even when i specify it to be printed collated
There are no exceptions thrown and the program compiles with no errors.
Am i calling java multi-platform print dialog and adding the
attributes correctly?
Is this a bug or am i missing something for both my questions?
This program was run on java 1.4.6 and 1.5.0_06 with both producing the
same results
I really hope someone can help me with this problem
Any help is greatly appreciated
Thank You
Yours Sincerely
