Check the page-orientation setting
Make sure the media size and page orientation selected in the application match the
settings in the printer driver. For more information, see Print.
Check the printer location and length of USB cable
High electromagnetic fields (such as those generated by USB cables) can sometimes
cause slight distortions to printouts. Move the printer away from the source of the
electromagnetic fields. Also, it is recommended that you use a USB cable that is less
than 3 meters (9.8 feet) long to minimize the effects of these electromagnetic fields.
If the above solutions do not work, the problem may be caused by the inability of the
application to interpret print settings correctly. See the release notes for known
software conflicts, refer to the application's documentation, or contact the software
manufacturer for specific help.
