You need to properly configure your Word document to print in a way that the printer can understand. Right now you likely have two competing configurations and the one you dont want is overriding the other.
Word has 2 printing configuration areas. The Word specific document only printer options that are normally under File > Print > Page Setup > Paper and the normal printer driver configuration area under File > Print > Printer Properties. Synch up these two options and you will be able to print as you intend.
