Need INF driver for server port HP 5600 printer Win 7  

I am trying to set up a printer port to access a Linksys PSU4 print server. The print server works fine as it is being used from other computers on my home network. I have been trying to set up a spare eee netbook pc with win 7 print server but cannot set up the HP 5600 print server port. Every time I try to add a print server port to the printer it requires a INF file. I cannot find this file on any of the HP 5600 install disks.
Any suggestions on how to add a print server port. I have searched the web and it appears other people are having the same problem but not very helpful suggestions.

Thanks Bob

Not solved but have a workaround.
I stumbled on the IP address of the print server. Instead of trying to create a print server access port I created a TCIP/IP address access port. Now when I print I have to make sure the printer is on the right network by selecting find printer in the print window.
I would prefer to have had the INF file to just print, but I have spent way to much time already. I hope this helps others.

OK finally solved seems like I was looking in the right direction with TCP/IP. I have included a link to Linksys on how to set up the port
