Printing to 58mm (tolerance+0/-1) thermal paper using a Seiko Industries MTP201-G166 print head with bitmap capability, these machines were also used by many instruments from manufacturers other than HP. Its influence can still be seen today where many equipment and thermal printers still use protocols derived from those first used on the HP 82240.
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.
