Window's Vista firewall can block certain Lexmark software processes. However, Microsoft has provided a feature which allows network printers and multifunction printers that rely on these processes to communicate effectively over a network. This article describes how to verify that these exceptions are listed and turned ON.
IMPORTANT: If turning OFF the firewall allows successful communication with the printer, this procedure should be utilized as the proper remedy for this type of communication issue. Click here for an article explaining how to disable the Windows Vista firewall.
NOTE: It is not recommended that you leave Windows Vista Firewall turned OFF unless you are actively running third-party firewall software solutions. Third-party applications can also cause network communication issues. Click here for an article describing this possibility.
