Every operating system in the house supports my nearly 20 year old HP 1022n (which I probably print to weekly) out of the box. The last time I used my 30 year old LJ4 probably 3 years ago, it worked fine (for Win7 and IOS). I bet I can still print to an LJ-II if I still had one. Did they remove PCL and Postscript from HP printers in the last decade?
