HP Printer With US Robotics Router

Glady:

That was very detailed.

Normally, the port that is used by IPP printing is 631. Perhaps you can do a
port scan on the US Robotics router to see if the port that you're using
(1631) is open. To do this, open a console window and type in the following:

nmap <Router IP>

You should replace <Router IP> with the IP address of your router, which
from your message is: 192.168.2.1 (right?).

About the PPD directory error that you're getting ("/opt/share/ppd": no such
file or directory), I noticed that I also got that error message when I
tried to configure the printer using the CUPS interface directly, i.e.,
http://localhost:631). But when I set up network printers using the gnome
printer applet, everything worked. You'll find this under the menu item:
System -> Administration -> Printing.

Let me know what you get with the port scan (nmap).
