We bought one of the first home lasers. Cost twice as much as the PC we attached it to and then I had to buy an expansion card and RAM in order to print the graphics heavy papers my wife was producing. Details are lost in the mist of time… I believe it was a big pile of 4164 chips to expand the memory to a full 1Mb.
One thing I do remember was the month it took to get a single page out of a parallel port.
