Cannot Print on Samsung Tab 4

So I'm a tech trying to figure out why a friend's tablet can't print in specific scenarios. It can print pictures and files from gallery and such. If I wanted to print an email from any Gmail or the basic mail app it goes into the preview panel where you would select pdf printer or whatever plug in you use. If you select anything but pdf it Says, " Failed to change settings. Try again." then locks up that screen. Any ideas?

Hi, so what else are you trying to print other than pdf? and are they all from Gmail?
