Missing printers in wx.PrintDialog

We are finally migrating our old workstations with Xubuntu 9.04 to Xubuntu 10.04, and in the process we're testing our in-house wxPython application on the new systems. Everything works nicely, exc开发者_如何学Pythonept that wx.PrintDialog's popup shows NO printers available, there's only a "Default printer" with empty "Device" and "Status". This happens even with wxPython's PrintDialog demo. What could I check out?

(Xubuntu 10.04, wxPython 2.8.10.1)

It looks like you have to install libgnomeprintui:

apt-get install libgnomeprintui2.2-0
