print to pdf and got it cropped

Good day to everyone.

Basically, the problem is that after using the 'print' function to export as '.pdf', i got the figure on it cropped.

1st. for printing i used the following:

%My figure handle was named as 'hfig1'

%Margins

SupMargin= 1.0;

InfMargin= 1.1;

LeftMargin= 2.0;

RightMargin= 0.2;

% Settings to print in A3 landscape paper

PaperWidth= 42.0;

PaperHeight= 29.7;

Width= PaperWidth-LeftMargin-RightMargin;

Height= PaperHeight-SupMargin-InfMargin;

set(hfig1, 'PaperUnits','centimeters');

set(hfig1, 'PaperSize',[PaperWidth PaperHeight]);

set(hfig1, 'PaperPosition',[LeftMargin InfMargin Width Height]);

set(hfig1, 'PaperOrientation','landscape');

print '-dpdf' '-r800' 'PDFfileName.pdf';

winopen 'PDFfileName.pdf';

2nd. After being executed i got a half cropped figure from beneath. The weirdest thing is that if after all the script is executed, and then i (first) bring the figure window to the front, and (next) i execute just the 'print' script part , it works like a charm (great!!)...

However, i don't want that to happen because all my scripts (others similars) were tought to run like "calculate...plot...print....save...gotonextscript". As a batch i think.

To add relevant information:

-Matlab R2014a 64bit is used

-Each of my scrips has 1500 lines aprox

-Even if '-r0' DPI is used for printing, the result is the same

-Figure has [4x5] suplots in it

That's all. Please, some help. Have a good day
