I don't get it. The line

[status, output] = system (sprintf ("if exist \"%s\" ( exit /B 1) else
( exit /B 0 )", ghostscript_binary));

will check for the existence of "gswin32c" in the current directory.
First, it should be "gswin32.exe". Second you will never have "gswin32c.exe"
in the current directory when using "print" in normal situation.
