printer trouble

I'm on SuSE 9.0, my printer is an HP Photosmart 7450.

The printer was working fine yesterday. I've got a dual boot setup, and I went over to windoze today and installed my printer there.

When I rebooted to Linux, a strange thing happened. My printer jobs quit coming out, they just sit in the queue.

select the printer, and click on test, the test pages come out **FINE**, both the text test page and the graphics test page. So the printer's happy and the connection is working.

usbview shows the printer is there. It's in a red font, whatever that means.

When I try to do anything on that web page, it prompts me for my username and pbuttword for CUPS. I give it my username and pbuttword and it prompts me again. I give the root username and pbuttword and it prompts me again.

I've tried rebooting several times, with and without a hub. I was using a cheap Chinese USB 1.1 hub. It was working through the hub yesterday, but my Zip drive got upset whenever the hub was there, while when I removed the hub and booted again, the drive started working again. Right now the printer is connected without going through the hub and lpq still says "printer is not ready".

I figure the problem is that the printer queue has probably gotten itself into a weird state that rebooting doesn't cure. Any ideas how I can get it straightened out?
