In order to use an HP Deskjet 3535 printer, I have installed HPLIP under Fedora Core 4. The printer works nicely. However, when I try to use the HP Device Manager from the GNOME Desktop, nothing happens. If I use the command line interface I get an error, as follows: [root@sucre gmata]# /usr/share/hplip/toolbox Traceback (most recent call last): File "/usr/share/hplip/toolbox", line 41, in ? import base.async_qt as async File "/usr/share/hplip/base/async_qt.py", line 85, in ? from qt import * ImportError: No module named qt [root@sucre gmata]# What could be going on? Thanks in advance. Gustavo J. Mata
