TPostScript, empty pages are created in between real pages

	Hello,
	I have a program that creates a postscript file. But whenever I do

NewPage, some empty pages are created in between the real pages. So i have extra empty pages. It is not problem only it makes the file look liitle bit uglier. I pasted the part of the program that I create the postscript file below. It is rather long but basically it is a lot of Draw and Set commands. I played with the
places of NewPage() commands, and also c1->Update() and c1->Modified() commands... Nothing helped. I assume i am doing some very basic mistake here. I appreciate your help. Thank you.
