Hi Alan
I've had a similar problem using Adobe Acrobat on a web server. I tried the same solution and came up with the same results. I posted questions on the Adobe boards for solutions and ended up raising a stink regarding the EULA. It (at least at that time) forbid such things. So... I tried the AMYUNI PDF driver - that worked great once I got around all of the user/security issues. My routine printed without the report generator, but I don't suspect that that is the cause of your problem.
Good luck,
Erik
