Hello, I'm hoping someone can help me with this one as its causing me a serious problem. I'm running a basic 2d CAD program in Windows 7 via Parallels 10 on OS X Yosemite. The program works fine up to the point when I come to print. I set the page and paper size within the CAD program to A3, select print preview to check its ok and then print. The A3 page passes through the printer but the drawing is always reduced to an A4 size, very very frustrating. This is a major problem for me, as most of my drawings are A3. The printer I am using is a Canon IX6850 which is wirelessly connected to the Mac. I gather from other forum posts and google searches that this must be a printer driver problem. Parallels appears to assign default driver (HP Color LaserJet 2800PS) to handle the printing. Unfortunately I cannot alter this and there is't an option to change the paper to A3. Please, please can someone help me with this?, I've wasted so much time trying to rectify it this week and I need it to work. Many Thanks, Oliver.
