garypch, welcome to
RP.
well, you did a good job of handling the noise. in the process you've lost a bit of definition and left a bit of clone marks. nonetheless, it shld print out pretty well.
first thing i would do is add a bit of 'clarify' to bring the image out more. this is also going to bring the noise out more too. if you're using photoshop, i'm not quite sure what the equivalent is to 'clarify', but you could use a brightness/contrast adjustment level that shld come close. you want to bring out the detail first, as this will make other steps easier.
attached is my workflow and image of this.
