Used HP 82240A infrared printer in excellent cosmetic and functional condition.  It prints from an HP calculator with infrared output.  A generic AC adapter is included to allow printing with or without batteries.  A few feet of printout using my HP 50g calculator is left on the printer to show typical print output using batteries alone or  the AC adapter alone.  Batteries not included.  Rolls of 2-1/4" wide black printer paper are available at several stores.  This is an older model of the HP 82240B infrared printer and does not have the red LED to indicate when the printer in on; it does, however, have a larger font which I prefer when I print since my 19-year-old eyes are 60 years in the rear-view mirror!
