From computer (1), I could still print from my Microsoft Office products, but other printing was prohibited. A non-functional ?add printer? icon was the sole occupant of my "printers and faxes" window.
I searched the internet for solutions, seeing that others shared this problem as well with no effective solutions. Reimaging (the OS) seemed the only answer; lots of software, big job, there had to be a better solution.
Looking at my computer properties, I noticed that I had not yet installed SP3 on my XP OS as I didn?t trust it when it was first released. I downloaded and installed the service pack, rebooted & opened the "printers and faxes" window to see the problem resolved. All the missing printers and fax items appeared and are so far, fully functional.
