V305 Printer and Vista Give "Communication Not Available" error

I was asked to start a new tread that way my issue doesn't get mixed up with someone else who had the same or similar problem as me.

I have a Dell Vostro 1510 laptop that is connected by USB cable to a Dell V305 All in One (Printer, Copier, Scanner).

I've been using the printer for at least couple of years with the same laptop and never had a problem printing. But several months ago, all of a sudden started to receive "Communication Not Available" error from the printer. I do believe the problem started after a series of Automate Windows Updates.

I went through the steps of get ting my system back to a restore point before the latest Windows Updates, and that only helped the issue I was having with my system working slow and screen blackouts.

I have Vista home edition 32 bit (SP2), latest Windows Updates as of yesterday, and latest Java. 

I have uninstalled, cleaned up all folders, and then reinstalled back the printer drivers  and also updates on Dell Printers several times.

I've run virusscan and spyware & cleaned the system of adware and such. 

Before that I had reinstalled my OS & all my applications & data.

I still have problem printing. I can print Test Pages & so far some web pages, but no PDFs or .txt  or .doc files!  I don't have a problem with copier or scanner, just the printer part.

Is there anything else I can try to fix the issue?!
