Thanks Grogan.

Okay, I finally locate it. No software installation is needed even though I ended up instilling a file called "pdf" and it shows up in the printer. But not sure what good it does, because I got the same result without it.

In the printing process, there is a little box for "print to file." All that is needed to to simply check off that box!!!

Previously I had been playing around and did install GenericPDF (or something like that). I removed it after my reading because I could not find anybody referring to it. That was a mistake; now I don't know how to reinstall it. Cannot find it. During that installation, it created a PDF folder in my Home Folder and automatically it saved the files there. Now I've to select the PDF folder to get there.

You are right on Acrobat. In Windows XP I was using Adobe Acrobat Professional 8 (which creates and views pdf files). There is no Linux version of such program.

I know from your postings you prefer KDE over GNOME. I'm trying to get use to one version, and I can experiment with KDE. (In Ubuntu you can install both. They "borrow" KDE from Kubuntu.

I do need answer, though, to the question: what about all the defensive and protective software like anti-virus, anti-spyware, firewall, etc. What roles do they play in Linux, if any?

Thanks.

Edit:
There are 2 KDE - one KDE, one KDE (mutiverse)
Any advise as to which is a better one to use?
