How to Enable the Socket Backend

[Matthias.Warmbold at gmx.de]

Hello,
I want to print to a HP Laserjet. The Printer is accessable over a TCP/IP-Network.

But I can't connect to the printer via cups. Because the backend "network socket" insn't enabeld. As you can see:
lpinfo -v
 network http
 network ipp
 direct canon:/dev/lp0
 direct epson:/dev/lp0
 direct parallel:/dev/lp0
 file cups-pdf:/
 network smb

The directory /usr/lib/cups/backend/ contains also no File with a name "socket".

My Question is, how can I enable the socket backend support?

For samba I've seen the following command

   ln -s `which smbspool` /usr/lib/cups/backend/smb.

Thanks

Matthias
