After more years of service than I can recall, my beloved HP LaserJet 4si printer has finally given up the ghost.
The machine printed 19 black and white pages per second and had two paper trays that, combined, held 1,000 sheets. I loved this feature because it eliminated frequent reloading of paper.
Even though it was ultra-reliable, HP discontinued the LaserJet 4si because of its massive size. So though mine is in principle repairable, you can’t get parts in a timely fashion any more.
So I have to buy a new printer for my Dell PC. I don’t need or want color. I need high speed black and white, lots of paper capacity, reliability, and ruggedness, since I print a LOT.
