I recently installed PCLinuxOS lxde on an old IBM T21 Thinkpad laptop with 384MB of RAM.
The install from LiveCD appeared to go well, and I did the full reload/mark all upgrades and install process in Synaptic Package Manager (SPM) as my immediate next step, but when I went into Control Centre to set up my printer I found the proper icon was missing, and an icon of a cardboard box with a '+' and '-' sign was there in its place, and clicking on it resulted in no action, and caused control centre to lock up.
Searching around the forum suggested I should search in SPM for task-printing
- which I did, and installed, but still had no joy, the icon was still absent and unresponsive.
Finally, the problem was solved by following the process given in this thread http://www.pclinuxos.com/forum/index.php?topic=99116.0
So, if after doing the upgrades process and installing task-printing, you still can't get the icon to function, go into SPM and:
search for and find task-printing
and mark it for re-install
search for system-config
and mark system-config-printer
Apply the re-installs.
Going back into Control Centre the proper config printer icon should be present on the Hardware tab and should now work when clicked.
I re-booted after doing the re-installs before going back into Control Centre but this may not be essential... as ever YMMV
