I forgot, I have even more...
There is a Commodore MPS 801 for C-64. I also have a Triumph Adler Gabriele 9009 daisywheel typewriter with IEC interface for C-64. The typewriter works, but I don't know how to get it "online" for printing.
I also have a Canon Bubble Jet BJ300 with ASF. That is a great inkjet printer, I used it a lot with my Atari ST computers, it emulates Epson LQ or IBM proprinter 24 pin, but with much better quality. Unfortunately the print head has dryed out, I have to find a way to clean it.
I have also ATARI SMM-804 9 pin dot matrix printer for Atari ST, this one is quite rare. I also have two ATARI SLM-804 and SLM-605. But none of those lasers is really operationally, one of the 804 has broken heater, and both have bad transfer drum kit. The one which is operative can print like a world champion, but you almost see no toner on the paper. For the 605 I have new drum kit, additional toner, but both have power supply problems.
SInce a few weeks I also have a compact HP laser jet 4 series printer with 2 MB RAM, 600 DPI, which works good, currently connected to my ATARI TT.
And my regular, ocasionally used printer on my current Windows boxes is also already almost vintage, a Brother HL-1450. (I don't print much, and I have some toner cardridges and drum kit spares as a few years ago one of my clients scrapped a douzen of these printers, so I grabbed what I need... This materials will last many more years) I think this HL-1450 was my best printer buy ever. I think I bought it in about year 2001.
There are also two small Oki LED 500 lasers, one is tested ok, but just 512 kB page memory is joke-less. The other is untested. Maybe I scrap them, I don't need them anymore since I have the Laserjet 4.
I would love to have a special thermo printer from Olivetti. I don't know it's model name, but it is from the beginning of the 1980's. It's not using any ribbon, but anyhow it prints on standard paper, by burning black dots in the paper. I saw it once, and it looks fascinating to observe this printer, as you can see little flashes from the printhead to the paper (and the metal plate behind the paper).
