[X4U] airport extreme and printing

[Robert]

I have a usb printer hooked up to an airport extreme. One computer can  
print no problems. The other on can't print. I have gone into print  
and fax and deleted the print and readded it. It shows up and tells me  
its there and what network it is on. It all looks right. When I go to  
print it tells me it is connecting but then it just sits there doing  
nothing. In the dialog box I even have hit pause and then resume but  
nothing happens. It has to be a setting but I can't find it. Both  
computers are running 10.5.2,. One is a Macpro and Its working fine  
and the other is a  Macbook Pro and its not printing. Thanks in  
advance. Bob
