linuxgeek: [nslu2-linux] unslung - cups problem

Hello,

I am new here. the last 4 weeks I searched several forums found by google, but didn't find a final solution, so now I try to ask actively ....

But first something about me/my Equipment:
About 3 years ago got my first NSLU2 - meanwhile I have 3 of them, all running under uNSLUng-6.10-beta.
First one in the basement, with 2 HDDs.
Second one below the roof, 1 HDD.
Third in my working room, with a 2-GB-Stick on Port 2 and a Samsung ML-1520-Laser directly connected to USB1.

Now here I come to the problem:

I started with a freshly flashed NSLU2, connected the Stick to USB2, moved OS to there, installed cups and customized it like described here:
http://www.nslu2-linux.org/wiki/HowTo/AddPrinter

Cups is running and accessably via browser from my net, but:

At my NSLU2 just 3 of the green LEDs burn, the one for USB1 is off.

The box knows printer is there::

Or maybe not ??:

I recreated both lp0/lp1 and provided all access rights (777):

Nevertheless Cups-Page tells me:
"Samsung_ML_1520 Ich stehe im Arbeitszimmer Local Raw Printer Angehalten - "Gerätedatei „/dev/lp0" konnte nicht geöffnet werden – No such device""

I at first entered my Samsung ML 1520 in the /opt/etc/cups/cupsd.conf, but when this didn't work I added a printer via the cups-Site - but both do not work:

Cups did not install a "printer.o"

Thats all - no idea how I get this to work. :-(

Before I had my printer connected by a lonshine usb server - but this wasn't reliable. Thought switching to cups was a good idea agains frequently asked question of my wife: "Is it printing?" ...

Do you think it might be enough to add "printer.o" in /opt/lib/modules/ ? And - where do I get it from ?

PLEASE HELP ME !!!.
