Thanks for any help.
I am using Reader 7.0 and want to print to file. I can successfully do so, but when I try to open the file (I save as .pdf) I get an error that says:
Adobe Reader could not open 'test1.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).
When I printed to file (I checked the print to file option on print of course) and I selected only a certain page. I have a pdf where I need to email different companies different pages of this document. I could print then fax, or print, scan, and then email, but I would of course like to do this way if easier.
How can I print to file, just a subsection of the pdf?

Thanks again.
