This is surely a problem with Wine and compatibility. If an applications installs fine on Wine, it doesn't mean that it will run normally as well. Bugs might appear or compatibility issues when the software requires additional files from the system. Try using Print Preview before you actually start to print. If you see the same image, rotate the picture to look like the final product and the software will rotate it normally.
I have downloaded the software and simulated a print job and everything was just fine. I also used the DEMO version on their official website.
