Page Margins on a PDF

I have a textbox on a form called Special Instructions, when I write large amounts of data in it and then view it in a PDF report its showing all the text ok but for example if Item 1 takes up 3 lines it doesn’t move the next product to a completely new line
So Item 2 is displayed on line 2 instead of Line 4, if that makes sense
Does anyone have any tips on solving this problem?

Heres the attachment

Thanks
