HPLIP-GUI won't run

[David McKenna]

New version of HPLIP allows HPLIP-GUI to be installed, but trying to run it produces errors. According to the HP website you just need to type 'hp-toolbox' at a command prompt. Of course that is Linux, so from an OS/2 prompt I did this:

[C:\]sh
# hp-toolbox
warning: python-dbus not installed.
warning: hp-toolbox should not be run as root/superuser.

HP Linux Imaging and Printing System (ver. 3.16.11)
HP Device Manager ver. 15.0

warning: No display found.
error: hp-toolbox requires GUI support. Exiting.
#

for some reason, it does not find a 'display'. Among other things, I also tried:

[C:\]sh
# hp-firmware
warning: python-dbus not installed.
warning: No display found.
error: hp-firmware -u/--gui requires Qt4/Qt5 GUI support. Entering interactive mode.
Traceback (most recent call last):

File "C:/usr/share/hplip/firmware.py", line 102, in <module>

mode = INTERACTIVE_MODE4

NameError: name 'INTERACTIVE_MODE4' is not defined
#

It looks like it doesn't recognize that QT4 is installed. It also acts like python-dbus should be installed.

the dbus warning can be worked around by adding a -x switch. Why it doesn't find PyQt I have no idea atm. I need to test this once locally. But as it's not needed for cups at all, it might take some time until I have time to try.

[Silvan Scherrer]

this workaround only worked for Qt3. for Qt4 it needs dbus. and as we don't have that yet, the gui stays nonfunctional. I will not workaround it, as I feel it's not worth.
Patches are welcome of course.
