Hi,

I have a HP Officejet 7310 printer with hplip 1.6.9. As I explained
recently, I can't communicate with the printer from any computer anymore.

hp-check doesn't show anything wrong. The output of hp-makeuri -ldebug
<ip> is:
hp-makeuri[3232]: debug: Trying IP address
hp-makeuri[3232]: debug: (xmit) Sending data on channel (3)
hp-makeuri[3232]: debug:
'msg=makeuri\nbus=net\nhostname=192.168.0.5\nport=1\n'
hp-makeuri[3232]: debug: (xmit) Reading data on channel (3)
hp-makeuri[3232]: debug: 'msg=MakeURIResult\nresult-code=12\n'
error: Device not found

I have traced back the error to the hpiod daemon which receives the
makeuri message but sends back a MakeURIResult with an error-code of 12.
Since the source code of hpiod isn't available I can't go any further. I
can the printer. I scanned the printer for open ports, everything is
normal. I tried restarting hplip, cups, the system but to no avail.

The /var/log/syslog file shows this information when executing hp-setup
<ip> as root:
Nov 22 01:16:45 hpiod: no JetDirect support enabled
Nov 22 01:16:45 hpiod: unable to read System::MakeUriFromIP
Nov 22 01:16:45 python: hpssd[2430]: warning: Inrecognized URI:
parallel:/dev/lp0
Nov 22 01:16:45 python: hp-setup[3365] error: No devices found.
Nov 22 01:16:45 python: hp-setup[3365] error: Error occured during
interactive mode. Exiting.

The printer used to work perfectly before it stopped working without
explanation.


Thanks in advance for your help.
