Interesting. I would have expected it to be some PostScript...

Sure, we have four HP LJ 8150s, with varying versions of things, but 
basically, three get the error and one survives with 
"root_ganymede_842" on the display.

I've sumarised the results here:

In all cases, there were two alternating messages before and 
after, "Ready" and "Tray N Empty" (2 <= N <= 4), because we never 
manage to have all our trays full :-|.

Interestingly, the one to survive was our oldest printer, with the 
oldest firmware and oldest JetDirect card.
An identical printer (of the same age as the oldest), on which I had 
updated the firmware, did not survive.

(Perhaps it forgot to to a mount before the fsck? or maybe (and more 
likely) it did a sleep directly after the fsck instead of first doing 
an unmount :-)

Will start wading into that PJL manual[1] ...
