Casio HR-8B printing calculator - displays P. instead of printing?

Anyone know if there's hope to print on this calculator again? Currently it won't do anything with the print function on, except display 'P.' Won't continue until print function is turned off. Would love it if I just need to push a button or two.
I'd actually be willing to repair the thing if need be, but by who? I like the basic functions - no frills (old style). Perfect for running a tape on my Schedule C taxes. I'm sure the unit is discontinued - replaced with more complex ones with bigger key pads, more functions, etc.
thanks
