These values are measured in pixels in 96 DPI (i.e. 1 pixel = 1/96 of an inch). When displaying on the screen, the actual distance is recalculated according to the screen DPI. Zooming does not affect the result.
To remove these distances, it's not necessary to assign 0 to these properties. Instead, you can include srvppdPageHSpacing and/or srvppdPageVSpacing in HiddenDistances.
