The 82143 printer uses the same adapter that's used with the HP-97 and the HP-41 battery pack: the part number is 82059A (or B/C/D.) This is an AC adapter (8V 3W max); the printer contains the rectifier circuitry (not inverter; that'd convert DC to AC.) However, to the best of my knowledge the printer will NOT work without a properly installed, working battery pack; the battery pack both stabilizes and regulates the voltage.
If you don't have a battery pack, you may try a STABILIZED 5V power supply (do NOT use a cheap multipurpose wall adapter) and connect its output directly to the battery terminals. You better make sure first that you have the right polarity, because reverse polarity can do permanent damage in a split second.

The charger for the 82143 puts out 8 VAC. It's the same charger that's used for the rechargeable battery pack for the HP 41 and for all of the HP-IL interfaces and MOST of the HP-IL equipment such as the 9114, 2225, 82162, etc. The charger for the US style AC outlets is a HP 82059. But there are other models for other countries with other styles of outlets.
