Basically I need to make a program that will print out the animal letters that the user enters into a textbox. I don't know how many letters will be entered so I need to get it after the button has been pressed to define the animals[]. But this doesn't work, the print dialog box opens and nothing appears. Yet if I specify that animals was String[] animals = new String[5] at the beginning, I will get 5 pages in the print preview. How can I get this to show without specifying it ahead of time? thanks for any help, I've been stuck on this for days.

Can you post an SSCCE that shows the problem? Because I've created my own little SSCCE and it prints out what I expect.

Ok, so here is a working example. when I type in "cat, dog, cow" and press printer, I see that nothing has happened in the print preview. There should be 3 pages with cat dog and cow on them. I'm not sure what's going on?

Hi

I think its because you are creating a new instance of BillPrinter and passing it to setPrintable : printJob.setPrintable(new BillPrinter());

Instead this you should pass this reference to setPrintable: printJob.setPrintable(this);
