Borderless printing is not supported on this model. When looking at the Page Setup tab in Printing Preferences in Windows, there is no option for borderless printing under Page Layout.

Models that support borderless printing will have a selection available for it in Printing Preferences.

When printing from Mac OS X, the Print window will allow you to specify the size of paper to print on.  For models that support borderless printing, (borderless) will appear as an option for paper sizes that support borderless printing.

Unfortunately, your printer does not have borderless options available as selectable paper sizes.
