Charles, 2cm is just shy of an inch That is close to MS default and should be adequate for any printer to handle.
If your page is being shifted approx .3 CM it sounds like you may have the gutter feature turned on. But it seems to be working in reverse. The gutter is supposed to be added to the "inside" margin to make the "gutter" wider to account for binding.
Go to Page Layout tab > Page Setup group > Margins drop down button > Custom Margins command (at very bottom of drop down) to display the Page Setup dialog, with the Margins tab selected.
At the top of the dialog make note of the left and right margin settings. Check to see if there is a value in the "Gutter" option, should be 0, and if the Gutter Position has been set.
So, if no gutter is set in Word, check the printer. Just under the printer selection dropdown there should be a hyperlink to "Printer Properties". The specifics of the properties dialog is printer dependent. Just look through it and see if there is a gutter setting in there that has been turned on.
