Webware features PrintWhatYouLike.com, a free site that allows you to pick and choose which parts of a website to print (the map, text, etc.) and what to leave out (Flash ads, blank space, etc.). From what I can tell you can't "work on" the site once its URL is added into the dialog box at printwhat youlike.com, but there is a bookmarklet that also you to use the tools directly on a page that already has the map of interest.
Sounds like this may be as useful to me as Jing has become.
