In some cases, your print might not be perfectly centered on paper. This can be caused by a misaligned print head or paper. To work around this issue, you can tweak the printer's print alignment which will shift the printed image a few pixels in any direction you wish and allow you to scale it as well to get a perfectly positioned print.
To do this, go to Settings, Printing, Printer Alignment.
Click on Print Test Page to get a baseline.
Follow the instructions on the printed test page to tweak scale and position till you are satisfied with print.
