last line of the page not to cut into halves

[Ngai88]

Hello,
Every time I print the page, I noticed the last line of the page is always cut into halves literally, leaving the top half on the 1st page and the 2nd half at the top of the next page. I tried to adjust the linebreaks but have not helped. Can anyone tell me how to go about resolving this? Is there some calculations involve with the margins so that it knows that there is not enough room to print the last line and so move the whole line to the next page instead? Thanks for any help.

Hello,
Presently when the print setup dialogue box pops up, the Left, Right, Top and Bottom all come with a default margin of 1" . I would like to change the Bottom margin to 0.82'. I looked up the ..........

//private const double anInch = 14.4;

So...I calculated to make it 0.82 inches, it is equal to 11.808...

private const double lessAnInch = 11.808;

yet when I go to compile and run it, the setups are still showing 1" for all. What else am I not doing right here?

Thanks,
Ngai
