Are you by any chance trying to print the same page that calls the print
method? parseContent executes the velocity code inside the page, so by
trying to parse the content you try to parse the content that tries to
parse the content that tries to parse the content that tries to parse
the content etc.
In other words: recursive call. Try printing the contents of another
document, like:
$xwiki.myPlugin.operate($xwiki.parseContent($xwiki.getDocument('Main.WebHome').content))
hoping that your code was not already in Main.WebHome...
