I usually just save things to my computer too, but now and then I do print them out. The most recent time was for an elderly relative who wanted to know about her father's life.
She doesn't have access to a computer or tablet (and her hands are so arthritic she'd probably not be able to use them) but she can read paper documents.
I printed birth, baptism, census, marriage, service, death, burial records etc to back up the 'timeline story' I did for her.
She loved it :-)
Many reasons why people want to print things, some just like a paper copy, we each work in ways that suit us.
