IE9 is unresponsive when I try to print a pdf file

I am using a HP Compaq 8200 Elite computer with Windows 7Pro and with 32 bit. This computer has Adobe Acrobat Reader XI and Flash player XI. Computer is setup to print to a networked HP Laser Jet 600 printer. When I tried to print a report Internet Explorer 9 became unresponsive and I never got a print out. Is the problem with IE9, Win7pro, Adobe or the printer? Any suggetions to resolve this problem is deeply appriaciated.

Thanks,

W.
