No chance whatsoever. The NeXT printer (note correct capitalization)
is nothing but a printhead; the NeXT computer does all of the work
rendering, sending data to the printhead at the correct rate, powering
up and down, etc. In order to use a NeXT printer with some other type
of machine, you'd need some sort of card which approximates a NeXT
motherboard and the NeXT operating system...
