The
Casio FP-12 printer listed in the external references is clearly not a
Spark_printer but a
Thermal_printer. The paper it uses is white (not metalised) which turns black under influence of heat (for example when lightly touched with a soldering iron). An example of a Casio
Spark_printer would be the FP-10.

It was known in the Spectrum community as the "astronaut's bog roll", due the silvery colour of the paper. 81.62.55.217 18:49, 14 October 2007 (UTC)
<blcokquote>I used to own one of these printers, as part of a TRS-80 color computer set I bought back in 2004. I think the printer was manufactured by Olivetti, but I can't remember, and I can't find any information on the internet. The manufacturer of the printer called it a "dry inkjet printer" but referred to the little glass rods as "toner rods." If you're a better searcher than I, please try to find it. If you have any questions, email me at tyson.brandes@gmail.com.
Shifted from a comment in the Casio section. Chris Cunningham (not at work) - talk 11:06, 23 June 2008 (UTC)
I wonder if these sorts of printers would be legal to operate nowadays (because of EMC considerations)? The ZX81 article hints that the ZX Printer had trouble in the US getting FCC approval. Richard W.M. Jones ( talk) 15:58, 25 August 2008 (UTC)
There was a spark printer, offered for about one year, that was the first printer that could do three lines per second. I don't remember the name. It used a 7x9 font. It did put out some fumes and the aluminized surface was a bit strange and there remained a bit of a curl to the paper. But it did work - and like the jump from 300 to 1200 baud modems, the jump from 10 or 15 characters/sec to 180 characters/sec was thrilling. Skipper2 ( talk) 16:08, 2 June 2013 (UTC)
