In my office, we have a Microsoft Server and about 15 networked LaserJet 4+s, with a few 5s thrown in. Although cheap to run and generally reliable, they are 20 years old and showing their age. I would like to start replacing them with newer laser printers, preferably all-in-ones (we do a lot of scanning these days). While there are some pretty inexpensive all-in-one laser printers out there (some of which are even iPad compatible, which is a real plus), I question their reliability as well as the cost of supplies. On the LJ4+s, the only consumable is the toner cartridge, which can be had very cheaply. Furthermore, since the printers are all compatible, I only need to stock one set of toner cartridges--a real savings. The newer printers seem to require drum replacement as well as toner cartridges, and they often seem to have "kill switches" that knock them out after a certain number of pages. Not good. I Suggestions for worthy replacements for the LJ4+s greatly appreciated.
