The "Add Printer" page of the CUPS Web interface is hanging...

[Dietrich Bollmann]

Hi,

I try to add a network printer from the CUPS web interface at:
http://localhost:631/ -> Adding Printers and Classes -> Add Printer
A page with the following content is shown:

  Add Printer

  Looking for printers...

  Local Printers:	 HP Printer (HPLIP)
  Discovered Network Printers:
  Other Network Printers:

...and the icon indicates, that the browser is waiting - but nothing happens...

What can I do?

Thanks for you help, Dietrich
