I sometimes print web pages into PDF files(from Firefox: File->print->Adobe PDF). I can highlight, underline and copy text in those files. But recently if I print web page I will get very large scanned images files. The files take a lot of storage space and I cannot highlight or underline any text in the file. The only changes happened to the software was several update through the Internet. I reinstall the software to get rid of the updates but the problem still exists. How can I fix this problem? I am using Windows 7, Firefox and acrobat 9 pro.
Thanks for your help!
