I used to use a Star NX1000 (Colour) dot matrix on my A2000. Circa 1990. Yes that's close to 20 years ago now. I think any Epson LX/RX compatible dot matrix clone worked fine with the Amiga. or the original dunnydoor printer.
These days a postscript laser or HP laserjet is fine. I have a laserjet 4 that works fine via the parrallel port.
I don't think there was an original Amiga printer. The CBM 1525 or MPS1200 ?. Epsons were more available and ribbons were cheap.
Cheers.
