Comment 63 for bug 96454

Another set of datapoints that may be helpful:
All under a clean install of Ubuntu 8.04 / HPLIP 2.8.2 / with a HP P1005.

1. Installing the printer with hplip results in the message:
 "Device is busy or in an error state.
 Please check the device and try again."
  and HPLIP Status tab says the printer is down "Service Request"
  and I cannot print a test page or download firmware to it.

2. HOWEVER I can print to it almost normally.
However jobs are never shown as completed and have to be manually deleted from thQ.
But I think this is a separate bug, cf http://foo2zjs.rkkda.com/forum/read.php?42,1207

3. Using sudo hp-setup -i
    gives exactly the same result as above.

4. Using the open source procedure in http://foo2xqx.rkkda.com/
   also seems to give the same result as above.
   the install seems to work, it prints ok,
BUT:
a. opening HPLIP again says the printer is busy or in an error state.
b. same error mentioned in 2. above.

5. Both methods 1 and 4 seem to cause the firmware to be updated,
as the printer seems to work again after being powered off in both cases,
but it is hard to be sure about this.

So there seems to be a problem in HPLIP 2.8.2 re detecting these printers as operational.
In my travels around the web over the last 36 hours (getting to this point)
many others seem to have the same problems mentioned in 1. and 2. above.

Hope this is helpful.
