The easiest way to send multiple screenshots, is to use Alt+PrintScrn to capture just the foremost window on your screen, then paste, Ctrl+V, the image into Microsoft Word. Repeat the Alt+PrintScrn and Paste process, to add more screenshots to the Word document.
(A single screen shot can just be pasted into an email without involving Microsoft Word.)
Now to send someone your Microsoft Word file, the easiest thing to do is go to: File tab > Save & Send > Send as Attachment
This method will save you the hassle of printing out the document and scanning it at the copier etc.
