Problems with print range from 1 to 9999 during printing

Question

Hi All,
In my project i am printing the datas in a JTable by a click of the button.I have used the following link:-
http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/advprint.html
to print that data from the JTable.The main problem i have is that
1) The font size in which the tableheader and tabledatas printed are so small.So that i need to increase the font size for both tableheader and tabledatas?
2)When i click the printButton for printing it opens a dialog box showing print range from 1 to 9999. And in the pages from 1 to 9999.
I don't want this.I want only 1 to 1.I know that by using Pageable
interface u can change it.But i don't know how to do it
Any one help me to solve this 2 problems i will be very thankful to u.It is Urgent.For ur reference i will provide my Code:-
