Windows Remove old printer software?

Hey all,
I have some old printer software haunting my mom's system. I had it set up to print over the network to my sister's lexmark in the other room, but that printer went with my sister to college. I removed the printer's entry from the "printers" folder (she's running windows ME ) and uninstalled all the software, or so I thought. I installed an HP printer today (which works just fine) and I'm getting spool32 errors in a lexmark dll on boot. What should I do to take care of this? I tried to delete the dll but it said it was in use. Is there a way to totally remove any trace of the old networked lexmark?

Thanks.

 

Well you can always go in the Registry

OR

Go in safe mode and remove anything in the boot up that involves the lexmark

 

use ctrl alt delete to find the lexmark drive end the process and then delete it
