IE8 and SP3 killed my Plug and Play USB Driver for Printing Suppor

Hello All,

Every since I installed Internet Explorer 8 and Service Pack 3, my printer
has stopped working. The printer still functions perfectly off my lap top --
without those updates installed -- so I know the printer and cable are not at
fault.

After nosing around the Device Manager, I discovered that the plug and play
USB driver for printing support is gone. After talking to Hewlett Packard
customer service about the problem, I am still at a loss.

So far I have (in this order) uninstalled the printer drivers, uninstalled
Internet Explorer 8, uninstalled Service Pack 3, and reinstalled the printer
drivers (rebooting between each step).

My printer still won't print any documents that I send to it from this
computer. Does anybody know what I should try next? How can I get my plug and
play USB driver for printing support back?
