HP LJ 1020: "ulpt0: offline"

[Graham Menhennitt]

I have a HP Laserjet 1020 printer that I've been using with FreeBSD 7
and 8 for the last few years. It's connected via USB as described in my
blog at http://menhenitt.com.au and it's been working up until today.

I just did a csup to RELENG_8 as of yesterday. After a make
build/installworld and build/installkernel and "portupgrade -a", it's
stopped working. When I power it on, I hear its startup noise and then
the second noise as the firmware is downloaded to it. After that, it
doesn't respond. CUPS reports "Waiting for printer to become
available..." and dmesg shows:

ugen1.3: <Hewlett-Packard> at usbus1
ulpt0: <Hewlett-Packard HP LaserJet 1020, class 0/0, rev 2.00/1.00, addr
3> on usbus1
ulpt0: using bi-directional mode
ulpt0: offline

The last line "ulpt0: offline" appears just after the firmware download.

Foo2zjs doesn't seem to have changed recently. CUPS has changed but I
doubt that's the problem. Maybe something to do with USB drivers?

Does anybody have any clues please.

Thanks,
