I’ve tried a test print here and don’t see any stray lines. This is a good looking file; clean lines, no defects that I can see other than the duplicated lion head. (On the other hand, it looks like you did not zip the SVG before sending it, which means that mail-handling programs can alter it.)
It *seems* like perhaps some pen-up commands are being ignored.
Some questions:
Are the places where you get the lines consistent from print to print?
If yes, and if you simplify the file to just those elements that are bridged, does it still give the same bridges?
If yes, can you get the the lines to change or disappear by using a much slower plot speed or increasing any of the delays?
