I need your help.... I am looking for the driver "HP LaserJet 4000 PCL 5e" (NT), not the " HP LaserJet 4000 Series PCL 5e". I have proven that there is definitely a difference, and have found the non-"series" to work for MANY printers. I have it in my Citrix farm, works great, but we have found a print server which we need this driver on. Chad Schneider Technology Analyst Bemis IT 920-303-7609
