I am using Debian Etch, Lenny. I tried to open 'HPLIP toolbox'; but the toolbox never appears.

See if you can get a meaningful error message by opening a terminal and starting the program with this command:

/usr/share/hplip/toolbox

error: PyQt not installed. GUI not available. Exiting.
warning: Qt/PyQt initialization failed.
error: hp-toolbox requires GUI support. Exiting.

is the important bit. You need to look for the packages for PyQt - probably a mix of Qt and Python will also be required.

Check to see if you have a package called python-qt3 installed.

Package memaid-pyqt

* etch (stable) (misc): memorization tool with optimal question scheduling
0.2.5-2: alpha amd64 arm hppa i386 ia64 mips mipsel powerpc s390 sparc

Package pyqt-tools

* etch (stable) (interpreters): pyuic and pylupdate for Qt3
3.16-1.2: alpha amd64 arm hppa i386 ia64 mips mipsel powerpc s390 sparc

Package pyqt4-dev-tools

* etch (stable) (python): Development tools for PyQt4
4.0.1-5: alpha amd64 arm hppa i386 ia64 mips mipsel powerpc s390 sparc

Problem
The package memaid-pyqt only exists in etch-stable, but I am using etch-testing

I already have python-qt3 installed

.
A python file will not work with the command './toolbox.py'

The command is
'python /usr/share/hplip/toolbox.py'
