Using Windows 7, after I open a PDF document and click on the print icon, the printer does not respond, yet I can print any other document such as Word or Excel and also any Web page. When I try printing the same PDF document using another computer running Windows XP to the same printer, it prints without any problem. I uninstalled Reader 9.3 and re-installed it with no success. I tried printing as image, also no response. Please help!
