[opensuse-factory] Problems with hp deskjet 649c

Hi to all, I'm new of this list, and i decide to subscrive here because I have some problems. I have installed openSUSE 10.2 beta 2 yesterday, it's all ok, yast is too much faster than the 10.1, but my printer ( a Hp Deskjet 640c) doesn't work with it. I try to configure printer with suitable module in YaST, and it showed to me a message, on my system there isn't package cups-drivers-stp , then this I went immediately to looked in YaST package manager, is true this package is not relased for this version, infact it isn't in the internet installation repository of factory too, now I ask to you, what I can do? Vincenzo P.S.:I'm sorry for my english, if is wrong, but i'm 14 and i'm italian, :-)
