I am having an embarrassingly difficult time replacing an HP 4600 Laserjet printer. What is your methodology for selecting a high-volume laser printer? [more inside]
Does anyone know how to put more memory in an HP Laserjet 4700? There is an access panel on the rear right-hand side, and four screws holding in two slot covers labeled EIO, I believe. I downloaded the service manuals but nothing in there I could use. I can pay someone to do a service call but it seems like it should be something I could do myself.
