The journal "Engineering" reported[2]:
"By replacing parts of the circuitry with two integrated circuit chips, room has been made for the printing mechanism
while keeping the size of the calculator down to 270 mm wide x 340 mm deep (10.5 x 13.5 in). The chips, one of which carries 750 MOS [Metal-Oxide Semiconductor] transistors, are being supplied by Plessey Microelectronics and Marconi-Elliott Microelectronics".
For some users, accountants for example, a permanent print of a calculation and its result was required. Early electronic calculators with printers were something of a rarity, and nine years after the introduction of the first ANITA electronic calculator this was the first ANITA with a printer. Though previously the company had filled this gap in its products by marketing the Wanderer Conti model which was manufactured in Germany by the Wanderer company.
