I only just discovered how to set the default Writer page size permanently to A4 borderless - by using the template. Unfortunately LO 4.2.3.3 behaves differently. When I print with borderless A4 page size, there is an error (“Could not start printer. Please check your printer configuration”). Although the page prints, there is an unprinted top and bottom margin of 12.7mm (1/2").
Several annoying menu shortcut changes/bugs in 4.2.3. A typical instance: Alt-F does not always bring up the File menu, and the second keystroke which used to be Alt-P now has to be ‘P’.
