Issue with print to pdf rotation

Question

I am printing to pdf in Windows 7. Lately, my documents rotate when printing. They are in landscape format before printing, but the printed document rotates 90 degrees. How do I prevent this?

Solution

This can most likely be changed in the printer preferences. Click File > Print..., then click Preferences in the printing dialog. That opens a printer-specific configuration dialog. You should be able to change the page orientation there.
