[Ti] network printing problem

[Dr. Trevor J. Hutley]

In my office, I have my Airport Extreme, which provides the wireless 
internet connection to my Al-book.

I have used the HP Laserjet wirelessly, connected to the Airport, all 
of last Semester.

It does not work now like that, for an unknown reason..
The Airport provides a flawless internet connection.

I can connect the HP Laserjet 1300 via USB cable to my laptop and it 
works perfectly.

If I connect the Laserjet to the Airport, my laptop can recognise it 
as a Rendezvous printer, by name, searches for a moment to 'create 
the printer' but always says 'there was an error adding the printer' 
(without saying WHAT the rror was).

When I then take the option of editing the printer list, I can Add 
the printer, it immediately sees HP Laserjet 1300 as a rendezvous 
printer, searches and then says DRIVER NOT INSTALLED.

What is happening here?  I presume the driver MUST be istalled 
otherwise I could not print from the USB port.  Is there something 
else that I need to do?  That maybe I did 5 months ago but have 
forgotten about?

I feel a bit helpless with all this technology but still having to 
use a USB cable....

Any advice would be appreciated.
