KB931836 and printer issue

I have a remote user that tried to install the DST update. Not sure exactly
what she did, but now her printer will not work. I have uinstalled the
update, and the printer and reinstalled both. When I go to reinstall the
printer, I get this box with this message:

KB931836 Setup
AVAILABLE SWITCHES;
[/help] [/quiet] [/passive] [/norestart] [/Forcerestart] [/warnrestart]
[/promptrestart] [/overwriteoem] [/nobackup]
[/forceappsclose] [/integrate; <fullpath>] [/log; <fullpath>]

/help Displays this message

SETUP MODES
/quiet Quiet mode (no user interaction or display)
/passive Unattended mode (progress bar only)

RESTART OPTIONS
/norestart Do not restart when installation is complete
/forcerestart Restart after installation
/warnrestart[: <seconds>] Warn and restart automatically if required
(default timeout 30 seconds)
/promptrestart Prompt if restart is required

SPECIAL OPTIONS
/overwriteoem Overwrite OEM files without prompting
/nobackup Do not backup files needed for uninstall
/forceappsclose Force other programs to close when the computer shuts down
/integrate: <Fullpath> Integrate this software update into <fullpath>
/log;<fullpath>Create log fife at <Mpath>

The only option is ok. Anything we try to print gets stuck in the print que
and can't be deleted. The only way is the shut the system and the printer
down. The printer is a Dell 920. Does anybody know what this problem is?
