auto-refresh not working in Device Manager

I have an HP Officejet 6700.

Printing is working fine, but in Device Manager, I find that auto-refresh doesn't seem to work, when viewing "Printer Control".

The manual Refresh button on that tab works fine, but the view of the queue etc will not refresh automatically.

I have auto-refresh enabled, set to 10s, in Prefs.

This is on Debian unstable, hplip versiopn 3.12.6-3

hp-check is appended; it mentioned missing dependencies, but since this is a Debian install, and Debian's pkg manager is not aware of any missing dependencies for my system, I assume this is a mistake?

thanks much indeed.

regards,
calum.

This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]
