Printing Images

When you set the axes Position to [0 0 1 1] so that it fills the entire figure, the aspect ratio is not preserved when you print because MATLAB^® printing software adjusts the figure size when printing according to the figure's PaperPosition property. To preserve the image aspect ratio when printing, set the figure's PaperPositionMode to 'auto' from the command line.

set(gcf,'PaperPositionMode','auto')
print

When PaperPositionMode is set to 'auto', the width and height of the printed figure are determined by the figure's dimensions on the screen, and the figure position is adjusted to center the figure on the page. If you want the default value of PaperPositionMode to be 'auto', enter this line in your startup.m file.

set(groot,'defaultFigurePaperPositionMode','auto')
