C# App To print text file at 0,0 (x,y) coordinate of the page

[jigsmshah]

I need to print a text file .When i print it ,it is not printed exactly form 0,0 coordiante of the page. I mean the top most left corner.It is leaving some margin from top and from left.The code is an example from MSDN.
I am using c# 2.0 and VS 2005.I have just chaged the X coordinate for the DrawString function.i am using it as 0 and the Y coordinate is calculated.

This is just a test application, as i have to take the printing logic futher to print business check images.With image also i was getting some space on the left and top side.
Can this space be controlled or it by default ?
When i am printing it to Microsoft Office Document Imaging or CutePDF Writer i am not getting any space on the left and top side.When i print it through printer i am getting the space from top and left.
I have given the X coordinate in the DrawString function as 0
and i am varying the Y coordinate.

Thanking you all in advance.
