HP Laserjet were pretty good even pre-2000. I spent some time in publishing. And I'd compare it to nowadays paper feed on a $100-250 ink jet, that has couple of springs (id 3mm, L=15mm) that would just fail and the printer won't take paper any longer. Virtually no printer in that price range has replaceable rubber paper rollers.

Indeed- I only used 2000 as its now the last year for any patents to have been around. But all-in-ones, network printing, duplex, color-laser, were all around in 2000 and any fundamental patents on them should have expired. Wifi integration maybe not, but this seems pretty trivial to "clean room" in this day and age if this is somehow patented functionality.
