I have a strange problem with HP drivers. I have configured a HP printer 2025dn with LAN connection, on 3 PCs, using the CD ROM of HP driver.
All works well, but sometimes for certain documents the time for printing is very slow and long. I observe during this situation, in task manager, a process called
rundll32.exe loads CPU at 100%. If I kill that process the printer starts printing fast the document in the queue.
