Print As Image Tips on printing: When printing pdf files on some printers, especially Laser Printers, it is best to check the "Print As Image" box on the printer pop up menu: Select Print, and on the top right hand portion of the menu, there are 3 to 4 boxes. Check the "Print as image" option. I've noticed that the error in printing occurs in files with equations or drawings. But some HP inkjet printers don't have this problem...its mostly the Laser printers that mess up.
