If you have been experiencing problems printing (in particular with very slow printing) with ZoneAlarm installed, we recommend you try the following:

Open ZoneAlarm and go to AntiVirus/AntiSpyware on the left and then click the Advanced Options button on the bottom right. In the Advanced Options window, click Exceptions under Virus Management ("not" Spyware Management). Click "Add File" and copy and paste in the following line and click OK:
C:\WINDOWS\system32\spool\drivers\

Restart the computer and test printing again.

Please also let us know the printer brand and model you have been experiencing these problems with.
