You may have selected the wrong *type* of printer connection when 
setting up the printer. Most HP All-in-One or MFC printers appear on the 
network as 'socket://192.168.1.xx:9100' while LPD printers appear as 
'lpd://192.168.1.yy/CONNECTOR' where CONNECTOR is something like 'DUMMY' 
or PASSTHRU or PORT1 etc. And I have a Brother printer connected 
wirelessly only which appears as 'usb:/dev/usb/lp0' on my computers. 
Note that none of these have an actual "server" machine. They act as 
their own server. In fact the LPD printer, is connected by a parallel 
port cable to a 'Print Server' hub which does all of the server stuff.

I strongly suspect that entering the IP address alone, without properly 
denoting the type of connection, will always fail since the driver will 
talk to the wrong connection.

You might try setting up the printer using cups on your desktop machine. 
It seems to be quite competent at finding and recognizing network 
attached printers. Use http://your-computer's-IP:631 from a browser. Of 
course, if you are not running cups, this will not work.
