I got a 82143 printer for the HP41 without battery. I would like to use standard NiCd rechargeable batteries. How much cells of 1.2V do I need? Some experiences?

Actually on the '97 you don't have to take the feet off. All the screws are nestled all snug in their little holes... and I do mean snug.

Use the right size screwdriver. I've seen a lot of stripped screwheads on the '91 and '143A where somebody used the wrong tool. |
