Managed to solve this one by using the native drivers rather than the UPD. Kind of strange as it worked ok with other applications and not printing with the Java one.

Its strange it works ok for IE but not for the java application. Is there an easy way to map all the driver to a 5si?

We have used HP LaserJet 5Si for laser printers and this has worked real well. We have seen some printers do not like the UPD print driver.

From the browser users login to a java application which opens in a new window. From the IE users can print, from the java application the user can see their printer but the print job does not print! I can see the job goes through the local spooler but nothing to the printer. The users are using UPD. Any ideas? I saw a few bits on the Citrix Forums with people with the same problems but no one had posted anything useful on the reply's. Thanks, Chris
