Windows 7 Can't print to printer, can't run troubleshooter, ca

[Mysticle31]

I have an HP 2730p Tablet with an HP OFficejet 7310 printer. I've installed Windows 7 on it.

This morning I come to find my printer won't print. I select print in any app and nothing happens. No activity in the que.

So I try to print a test page and I receive "Test page failed to print. Would you like to view the print troubleshooter for assistance. Operation could not be completed (error 0x0000007a). Now my printer works. Other networked computers print to it, and the 2730p printed to it in Vista. As a matter of fact, the HP own diagnostic page and alignment functions print and work.

OK. I restart spooler and tried direct printing. Nothing. I deleted all the printer drivers in printmanagement.msc nothing. I deleted all the files in the spool folder in system32. Nothing. The spool service starts and stops with no errors.

The printer will install with HP's installation program. It won't print. If I install the printer with Windows 7's Add a Printer I receive.

Also, when I tried to use the Windows Troubleshooter I find it fails too. "A problem is preventing the troubleshooter from starting. Package ID: DeviceCenterDiagnostic. Path: Non-local Package. Error Code: 0x800703EE. ...."

I'm out of options. Any advice? I suspect all these problems are related. They have the smell of a permissions error but I don't know what or how to diagnose any more.
