Comment 63 for bug 42802

The problems seem to persist with the new cups 1.2.1. package

Here is what I have done:
1. deleted all printers
2. installed cups 1.2.1. using apt-get update / upgrade
3. installed the network-printer manually using gnome-cups-manager and the recommended postscript-driver
4. changed the options of the printer (from letter to A4)
5. printing a testpage using: http://localhost:631/printers/ the following message appear beside the selected printer
"/usr/lib/cups/backend/http failed"

Here is the output from the (standard) error-log:
