access from cups to a remote printer with authentication?

["Stefan" <giftzwerg@fantasymail.de>]

Hello,

how can I access form cups with IPP (Internet Printing Protocoll) to a
remote printer which requires a login (Basic Authentication)?

I've a cups installation and I add a printer class for a remote printer
(ipp://192.168.1.10:443/printers/HP/.printer). The remote print server
requires a login. But I don't know, where I can set the login
information. 

Thanks.

Stefan
