Print historical charts

 
I read about the WindowScreenShot but I can't guess how to use it to print the historical charts .Say I want to use 15 min time frame and  print the last 20 days  charts .Every day to a .gif file .Any help ? 

 
Best way I can think of to so this is turn off autoscroll, scroll back manually to the timeframe you want to show, and use your computer system's printscreen capabilities, or get a program that has screen capture capabilities and do it that way.
 
Thank you JD4 . Seems to be  the best solution !The manual printing in metatrader itself is limited.
