content: The Japanese firm of Canon Incorporated introduced a printing electronic calculator, the P10-D, in 1978. This is a lighter version of that machine, with a narrower paper tape, that apparently was introduced in the United States by early 1980. It sold for about $75. In mid-1980 Canon advertised that it sold five versions of its “printer display” or “PalmPrinter” electronic calculators. At least three of these, including the P7-D, were still on sale in 1985.
