In case anyone is still experiencing this problem...I recently was troubleshooting the same issue. I am using AutoCAD 2011 on Windows 7 (64-bit) OS. My printer is HP LaserJet 5200. I had tried absolutely every single driver available, until i found one that worked.
HP came out with the newest drivers on Nov 22, 2010:
- HP Universal Print Driver for Windows PCL6 x64
- HP Universal Print Driver for Windows PCL5 x64
- HP Universal Print Driver for Windows PostScript x64
I was using the PCL6 version for a couple days, and it seemed to have solved the problem. Unfortunately it was still acting up every once in awhile. Now I installed the PCL5 version and have had no problems.
Hopes this helps anyone out there that is still trying to solve this issue.
