In a mean time I have discovered another problem: nothing is coming out of the printer with the same file, when zoomed to extents (at 1280x960 screen size zoom is about 5%), with larger zoom factor printing is done ok. It means that, for some reasons, there is no information to be reproduced is received by the StretchDraw function. Any ideas?
