The printer is powered by four AA batteries and can accept alkaline or NiMH cells. External power is supplied via a common nonpolar 5.5mm/2.1mm AC jack. The manual calls for 9-12V AC or DC at 500-1500mA and thus can be used with most common barrel jack power supplies. The original power adapter HP 82241A is rated for 9V AC at 13.5VA. The printer works on either internal, external or a combination of both. It is rated for 6000 lines of print on fresh sets of internal batteries. | The printer is powered by four AA batteries and can accept alkaline or NiMH cells.

The IR receiver diode is mounted to the bottom left of the printer when viewed from the top, hidden behind an IR window. Printing distance is dependent on background IR levels, with correspondingly shorter range under incandescent fixtures or in sunlight. It is usually possible to print at 15cm or more when the IR diode is in field of view indoor. | The IR receiver diode is mounted to the bottom left of the printer when viewed from the top, hidden behind an IR window.

Maximum time to print a line is roughly 1.2 seconds with AC and 1.8 seconds without, accounting for the movement of print head. | The printer was designed with a 200 bytes buffer, and as it is only set up to receive information, it is up to the controlling device to ensure long printouts does not cause an overflow. Maximum time to print a line is roughly 1.2 seconds with AC and 1.8 seconds without, accounting for the movement of print head, thus 1.8 seconds is usually set as the default DELAY value on calculators. | ||
All variants were manufactured by the Singapore division of HP. | All variants were manufactured by the Singapore division of HP. | ||
