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.

> $ lpq
> printer is not ready
> Rank Owner Job File(s) Total Size
> 1st noone 16 .bashrc 3072 bytes

> $ lpstat
> printer-16 wguava 3072 Mon 21 Feb 2005 12:09:46 PM PST

> $ lpstat -p printer
> printer printer disabled since Jan 01 00:00 -
> Unable to open USB device "usb:/dev/usb/lp0": No such device

> $ ls -l /dev/usb/lp0
> crw-rw---- 1 root lp 180, 0 2003-09-23 11:01 /dev/usb/lp0

When I go to the SuSE control center, select hardware->printer,
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.

I tried looking at http://localhost:631, under "manage printers" it says

> Description:
> Location:
> Printer State: stopped, accepting jobs.
> "Unable to open USB device "usb:/dev/usb/lp0": No such device"
> Device URI: usb:/dev/usb/lp0

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

I uninstalled and reinstalled my printer, and the problem went away.

I then rebooted my machine and printed again, just to make sure that the
reboot didn't screwing up the spooler. It didn't.

Everything appears to be OK now. Alles in ordenung.
