I have a rather unique problem (or at least for me it is). I am working on a friends computer he has a Dell Laptop (XP home, NAV 2005) that connects to Dell Wireless Router. I have connected his printer (dell 720) to a HP 310 JetDirect Print Server using LAN port 2 as a Ethernet Connector to the Print Server. The printer will print the entire job you send to it however the Dell Print monitor hits 99% and stays there. You have to delete the job manually and reboot the system in order to print again. I have updated the driver for the printer and used all tricks I could think of. I am pretty sure it is the print server as everything works fine if you are connected directly. I like to think that I am fairly knowledgeable about computers but this has me stuck.
Thanks for all your help
