Ok, I'm gonna run to my car and get the manual for the terminal I'm 
talking about....

>From the "IBM 3197 Model C Color Display Station Setup Instructions".  
Page 76, step 9.1.9: "If you have a printer (IBM 4201, IBM 5201, or IBM 
4202), attach it to the logic element of your display station."  That 
caption is accompanied by a picture showing a printer connecting via a 
cable with a DB25-looking connector to the terminal.

I'd imagine that wasn't meant to be used for printing labels, form 
letters, etc, like the bigger coax/twinax printers that IBM sold were 
meant for.
