[newbie] Cups-printing-problems

[Thomas Walter]

I have Mandrake 7.2 installed. After installing my HP Deskjet 815C on lp1 
with Printerdrake everything works fine, but after reboot I can't print or 
get a connection to the cupsdaemon via localhost:631. While trying to install 
the printer with Kups I get the message "no port detected on this computer". 
If I run printerdrake before I get all my ports (parallel and serial) back in 
Kups. 

What have I done wrong?
