A printer’s toner cannot be used to tone up a person’s body, but there has been a joke:
 
“The man leaned on the printer cartridge because he wanted to tone up his abs.”
 
The joke was posted on the website Pun of the Day on August 22, 2011.
 
“Why did the printer go to the gym?”/“To get toner” is another “toner” joke.
