... Also, the best I can find out about the duplex is that it is "manual" -- I can't find out whether that means "manual setting on control panel" or whether it means that you have to manually reverse and turn over the sheets of paper, after printing the odd page numbers, in order to print the evens! (Since that is precisely what I do right now, it would not be an advance).
Knowing what salesmen write my guess is it would be the latter.
At this point you'd be wondering what the difference is between a simplex printer and "manual duplex" one is. Perhaps none at all but it should mean the manufacturer has tested that when you feed the pages that have been printed on the first side back in to get printed on the reverse side they don't jam.
Nicely put ... ! Which means that the one I'm using at the moment (B&W HP LJ 1300, basically a very decent printer) is a "simplex printer" and not "manual duplex" in that sense -- though, more prcisely, jamming is rare; what happens is that if the sheets are put back in for the other side, you are likely to get 2 pulled through at once, which spoils the effect, as it were ...
I think this has something to do with static on the sheets, since leaving them lying loose for an hour or so alleviates it (without eliminating it).
The real work-round is to print the side 1 series, reverse the order and turn upside down, then empty the paper tray, place top sheet in the empty tray, initiate printing of the evens, and manually feed the sheets one by one into the paper tray once the previous sheet is pulled through.
Which possibly makes it a "manual duplex printer", in much the same sense as a dustpan & brush constitute a "manual vaccuum cleaner".
Thanks for the comments, Steve! Ted.
