My workhorse printer, a Hewlett-Packard DeskJet 720C, got a new black cartridge today, the previous one being spent, and it occurred to me at some point during the Align Cartridges routine that gawd, this thing is old, and indeed it is: I bought it (at Office Depot, I think, for something like $180) in 1997, which makes it ten years old, an eternity by computer standards.
And no, I have no plans to replace it; it works just fine, thank you very much, and you can still get cartridges for it with no difficulty. (In fact, recently at work we added a machine based on an HP engine using the same cartridge: the 45.) Further coolness: the 45 cartridge has a window in the front so you can tell how much ink is left in it, which is slightly more reliable than the current HP practice of popping up a dialog box on screen to tell you that it’s nearly empty, which in my experience it seldom is.
During these ten years, incidentally, I’ve gone through four DeskJets at work, following a few years with an old Epson 24-pin dot-matrix printer which is still in service in another department. By now it must be pushing fifteen. Ribbons for the Epson are not hard to get, either.
