HP 82204B Printer

Another tick box checked.   I purchased an HP 82240B Infrared Printer, which allow printouts from a lot of legendary HP calculators including (not an-all inclusive list) the 42S, 17B family, 32S family, 27S, 48 family, and the Swiss Micros DM41X and DM42.

The printer works on 4 AA batteries, I still have to buy an appropriate AC adapter for it.   

The printer works beautifully.   Check out the HP 82240B and some printouts using the HP 17BII+.
