Re: How to print in full page without margins

Hi Ron,
I tried that and it still not working. What happens is that the hard margin
returns .25 the printpreview shows exactly how the whole rectangle is drawn
around the hard margin. i.e., .25 from the left, .25 from the right etc. Its
nicely drawn on the printpreview. But somehow when I do actual printing the
printer adds .25 to the left of the hard margin. i.e. it starts drawing at
..50 double the size of the original hard margin.

To fix that I set the origins at margin to true. Since the graphics object
return now is located within the margin I start drawing the rectangle from
x:0, y:0 position. This fix the actual printing but the printpreview now
shows me it started drawing from the 0, 0 position. No hard margin is taken
into acount.

So I tested with different printer and found out that different printer has
different result again. Back to same old problem. The rectangle may sifted or
cut off on the right side etc.

Have you or anyone ever tried to print the rectangle of the hardmargin
(printable area). If so could you share information how this can be achieved.

I am using .net 1.1 and C#

Thanks Ron. Your inputs are greatly appreciated.

Ron, is it ok for me to do email exchange with you?

If any one from Microsoft reading this (hoping they visit forums), I think
its about time they provide a solution to this (if they have any) in their
MSDN or publish an article on how to do this exactly. So many people have
encounter problem with .net printing API behaving so differently on different
computer across different forums. This solution should offer technique for
printing the rectangle of a printable area hard margin that works with
different printer.
