I had an old very old HP LaserJet IIIP which has served me quite well, but yesterday it wouldn’t turn on. No lights, no fan, nothing. As dead as a Norwegian parrot!
It might have blown a fuse or lost the power supply, I don’t know.
Technical manuals for this kind of printer is hard to find, and in any case they’re not online. I’d have to buy it, and I’m not really in the mood to throw money after such an old beast.
I guess it is time to look for something newer. A native PostScript colour laser printer would be nice, preferrably silent and cost effective. Something like the HP Color LaserJet 2500 would be very nice indeed.
