A fun symptom
In ecom,
R. C. White typed: We did not get a printer with the original TRS-80 in December 1977, but early in 1978 the first printer arrived. It was a piezoelectric device that printed onto a narrow cash register-like tape using a process that I didn't - and still don't - understand, even though I've read Wikipedia's explanation. Would it be a thermal printer? I have had many of those and there was no ink, ribbon, etc. But it uses a heat sensitive paper to create images on the paper. Paper was glossy, expensive, and the printed image will fade in sunlight. Although the printers were cheap to manufacture and the paper wasn't out of this world expensive. So they were quite handy for a number of tasks. Lots of cash register receipts still uses thermal printers to this very day. -- Bill Gateway M465e ('06 era) - OE-QuoteFix v1.19.2 Centrino Core2 Duo T5600 1.83GHz - 4GB - Windows XP SP2 |

Was it that aluminised stuff? Thermal, I think. But within a month or two, we had our first dot matrix printer. This looked like later printers, but it had one unique feature that I haven't seen on any printer since: its print size was continuously variable. There was a knob on the back of the machine that adjusted the size of the printing. The I saw a Centronics (I think that was the brand) printer that had that. [snip] Sincerely, Gene Wirchenko |

Hi, Gene - and Bill.
Would it be a thermal printer? Was it that aluminised stuff? Thermal, I think. Yep! and Yep! and Yep! ;) Centronics printers came along soon after and had a good long run. The Centronics ribbon connector was outstanding. RC -- R. C.
