To print any of the MJ pictures do the following.
Open the hubpage
Click on the thumbnail (small image) to review and select the picture you want to print.
Click on that enlarged picture (this is not the slide show) and another somewhat larger image should open up.
With your mouse perform a right click and select "save image as"
Then save to your computer and print as you would any image or document from your own computer.
If you are watching the image via the slide show, as soon as the image you want appears quickly do the same type right click motion and again chose save image as. Then save to your computer and print.
