So you thought you knew everything about Texas Instruments scientific calculators. You knew that the TI45 was none other, but one of the many European variants of the incredibly successful TI30 line, this time a TI30 (or SR40 if you prefer), but with a green vacuum fluorescent display.
Guess again. This TI45 is a completely different type of animal: it is an LCD scientific calculator with a builtin thermal printer. I came across this machine by accident; although nonprogrammable machines aren't what I am usually after (I have, in fact, since traded this machine), when I heard that this is supposed to be an LCD printing calculator, curiosity overtook me and I made the purchase.
