But they did release a number of Postscript-language Personal LaserWriter models — the PLW 4/600, for example. I have printed to a 4/600 via a bridge daily for years from OSX. It needs the RAM upgraded to 6MB to work well, but it has never failed.

For big jobs I use a 12/640, but the nice thing about the 4/600 is the size, silence and low energy consumption.
