Windows 7: Canon MP530 printer stopped working, no drivers?

About three hours ago I tried printing from Word to my Canon MP530, which has been working just fine since I switched from XP to Win7 in mid-December. I got an error saying that there were no drivers installed.

I tried the Windows Update method to reinstall them - that failed. I went to Canon's site and got the current x64 version of the driver. That supposedly installed, but when I try to print anything including the test page I see 'printer not responding' in the print queue window.

In the Devices & Printers window it tells me I need to troubleshoot it. Running the troubleshooter tells me there's nothing wrong with it.

I tried removing and reinstalling the printer with the same results, also trying the new drivers.

I just got the firmware upgrade from Canon and have installed that; that didn't help either. It still wants me to troubleshoot it, and that has the same results.

Please help me. I really need to get some work done today, and I really need my printer to be working.

If it just stopped working like that, do not discount the possiblity that it may be time for a new printer.

Yes, I had given that some thought...

I tried removing the printer again, redownloading the drivers from Canon, adding the printer, shutting it down, reinstalling the drivers and turning on the printer. I'd done this in this order before with no luck, but this time it worked. No idea what was different.

Just as long as it is working. If it is getting old, as you begin to need ink, it may be wise to start looking for a sale.

The price of a new printer is not much more than a printer with the ink.

Good Luck with everything and thanks for the rep.
