Printing JPanel to fit one page, Urgent (thanks for help)..........

Question

hi all,
I am trying to print and can't get the right scaling. My problem is if the JPanel that has lot of images inside it is too big to come on one page width and height then I want the print out to be on one page. If my panel's height is too large to fit on one page and the width is only half of the page or less than page half of the width. Then I want to scale it's height only to fit on one page while keeping the width the same during printing and the images also to be scaled accordingly. And if my height is too small lets say less than half the page and the width is too large too fit on one page then in this case I want to print the original height or keep the height to be shown on the printout as it looks on the screen but scale the width to fit on to one page and the images also to be scaled accordingly. But my following piece of code doesn't honor this though it fits on one page. It keeps on increasing the width or height to fit the whole page thought the width or height is less than that and the images are also expaned accordingly. I want to scale the images too and only fit the width or height if any is greater than one page. Any help is really appreciated. Thanks in advance

double pageWidth = pageFormat.getImageableWidth();
double scaleFactorH = (panel.getSize().height)/(double)(pageFormat.getImageableHeight());
// set the clip to the size of one page
g2.setClip(0, 0, (int)pageWidth, (int)pageHeight);
// translate down the graphics object to the top of this page
g2.translate(0f, -pageIndex*pageHeight);
// scale to fit the width
g2.scale(scale,1.0/scaleFactorH);
panel.paint(g2);
return PAGE_EXISTS;
//method to calculate
public int calculatePageCount (PageFormat pf)
double pageHeight = pf.getImageableHeight();
double pageWidth = pf.getImageableWidth();
double componentWidth = panel.getSize().getWidth();
System.out.println("THe imageable width is " + pageWidth);
if (componentWidth > pageWidth)
scale = pageWidth / panel.getWidth();
double componentHeight = panel.getSize().getHeight() * scale;
printPageCount = (int)Math.round(Math.ceil (componentHeight/pageHeight));
return printPageCount;
Is there a way to fix this any help is appreciated.
Thanks

Dear Nadia,
Thanks for the info.
If I understand it correct I can make a copy of my actual css file.
Rename it this copy to e.g. print.css
And then make some changes such a letter fonts and colour
Linking this css file to my pages and specify it is only for `print1`
Right?
I`m using a template so if I amend the template like this and have all pages updated automatically that should do the trick?
Right?
Is there somewhere where I need to mention that e.g. the page needs to be reduced onto 95% by printing?
Or will the print.css do the trick?
Sometimes I get confused on what css can do and it can do a lot.
Many thanks for helping me out here.
Kind regards
martine
