|
dupHorizontal |
3 |

With horizontal duplex printing, the top of both sides of the page are at the same end of the sheet. With vertical duplex printing, the bottom of one page is at the same end of the sheet as the top of the next page.
This property relies on the printer driver, and may or may not be available on a particular printer. After setting this property, read it back to make sure the driver made the change, or check the Error property. If it is set to vperDeviceIncapable (7), then the printer does not support the selected setting and you should take appropriate action.
