controlling header size when printing

[miguel lisboa]

i gave a bird's eye at jtable printing in sun java docs
header's code:

 			Printable printable = getTabelaParaImpressao().getPrintable(
					JTable.PrintMode.FIT_WIDTH,
					new MessageFormat(titulo),
					new MessageFormat("Página {0}"));   

but couldnt find a way to control the font size of that header, when printing
where can i find out a solution?

thanks in advance
