Problem with PageFormat when printing

Question

Hi.
I use the following class to print large JPanels, but I have a problem with the PageFormat. For example:
I want to print a JPanel called labelPanel, so I write "PrintUtilities.printComponent(labelPanel);". It will now print this Panel on multible Pages, so I can put them together to see the whole Panel. This works fine, BUT I can't change the PageFormat. When the printDialog pops up I can choose a printer (this works), but if I change the page format (for example from "letter" to a bigger size) the PageFormat object stays the same as always, some kind of defaultFormat I think.
pf.getImageableWidth() always has the same value and I dunno why that doesn't work. Everything works, except changing the format of the page...
