First, you need to try update the latest microsoft office patch file from microsoft or you can open the MS Word, go to "HELP" menu select the update MS Word or related. Try the latest patch file first. You also can try windows update and select custom update, see their list have this problem solution or not. Second, you need to go to HP website download latest driver for LJ1020 and suitable use on Vista. Lastly, if still not solve the problem, you need this problem/issue to microsoft, ask their solutions. Kent

Annoying but easy to solve.
Go to the printer's ip address management page from a web browser. Look under the TCP/IP address settings. Click on the advanced selection. Disable the LPD Banner page. That should fix it, if it's not under advanced poke around until you find LPD Banner Page. ;)
